A grade school teacher with 33 students claims a ghost is the best explanation for the disappearance of an apple from the teacher’s desk. Assess the teacher’s rationale below.
The probability of any one of the 33 students taking the apple is an insignificant 3%. Therefore none of the students took the apple. Is it improbable that all of the sightings of ghosts are make up, so it is more likely than not that ghosts exist. Therefore we should default to a ghost being the most likely explanation for the disappearance of the apple from the teacher’s desk until someone proves otherwise.
The teacher’s rationale for concluding that a ghost took the apple is problematic for several reasons. Here is an assessment of the argument provided:
- Misuse of Probability: The teacher states that the probability of any one student taking the apple is 3%, which is calculated as ( \frac{1}{33} \approx 0.03 ) or 3%. However, this calculation is misinterpreted:
- The 3% figure reflects the probability of a specific student taking the apple, assuming there is no reason to suspect any one student over another.
- The proper question to ask is: “What is the probability that at least one of the 33 students took the apple?” This is calculated as the complement of the probability that none of the students took the apple, which is ( 1 – (0.97)^{33} \approx 0.64 ) or 64%. This indicates a much higher likelihood that at least one student took the apple.
- Logical Fallacy: The teacher’s conclusion that because individual probabilities are low, “none of the students took the apple” is a logical fallacy known as the fallacy of division. This fallacy involves assuming that something true of a thing must also be true of all or some of its parts.
- Assumption of Ghost Existence: The teacher assumes the existence of ghosts as a more likely explanation without sufficient basis:
- The premise “It is improbable that all of the sightings of ghosts are made up” is not substantiated. The existence of multiple reports of ghosts does not necessarily validate the existence of ghosts; multiple factors including cultural influences, optical illusions, and other psychological factors could explain sightings.
- The argument that ghosts are the most likely explanation until proven otherwise is an example of shifting the burden of proof, a logical fallacy where one claims something is true because it has not yet been proven false.
- Default Position: The default position in rational inquiry should be skepticism and reliance on evidence. The absence of evidence for the involvement of the students (or lack of evidence pointing specifically to any one student) does not automatically validate an alternative supernatural explanation.
- More Likely Explanations: There are more plausible explanations that should be considered before supernatural ones:
- Misplacement or misremembering by the teacher or another staff member.
- A student, or group of students, taking the apple without the teacher’s notice.
- Even if the probability of each student individually taking the apple is low, the combined probability is much higher.
In conclusion, the teacher’s rationale for attributing the disappearance of the apple to a ghost is not based on a sound understanding of probability or logical reasoning. Alternative explanations grounded in common everyday occurrences are much more likely and should be considered first.
The teacher’s reasoning has a few flaws:
- Ignoring the Most Likely Explanation: It’s far more probable a student took the apple (absent other info) than a ghost. Even with 33 students, the chance of one taking it is more likely than a supernatural event.
- Misunderstanding Probability: A low probability event (one student taking the apple) happening once doesn’t mean it’s impossible for any student to do it (considering all 33 students). The combined probability of a student taking it is actually higher than 3%.
- Lack of Evidence for Ghosts: There’s no scientific evidence to support the existence of ghosts. While ghost sightings are interesting, they lack verifiability.
- Burden of Proof: The burden of proof lies in proving ghosts exist, not disproving them. The simpler explanation (student took the apple) doesn’t require extraordinary explanations like ghosts.
Here’s a more logical approach:
- Consider if the teacher saw a student near the apple before it disappeared.
- Ask the students if anyone saw something or accidentally took it.
- Look around the classroom for the apple (e.g., under a desk).
These steps address more likely explanations before resorting to the supernatural.
How might the teacher rationally approach the disappearance of the apple?
To approach the disappearance of the apple more rationally, the teacher should consider all plausible explanations and assign credences (degrees of belief expressed as probabilities) based on available evidence and reasoning. Here’s a systematic way to do this:
Step 1: List Possible Explanations
- A student took the apple.
- Considering the collective probability that any student could have taken it.
- The teacher misplaced the apple.
- Considering the possibility of human error like forgetting or misplacing items.
- Another staff member took or moved the apple.
- Including cleaning staff or other teachers who might have interacted with the desk.
- The apple was thrown away accidentally.
- Considering scenarios like someone mistakenly clearing the desk.
- Supernatural explanation (e.g., a ghost).
- Included for completeness but should be approached skeptically.
Step 2: Assign Initial Credences
Initial credences should be assigned based on the plausibility of each scenario. These are subjective and should ideally be based on context-specific details (such as past incidents of items disappearing, the behavior of students, etc.), but a generic assignment might look like this:
- A student took the apple: 60%
- The teacher misplaced the apple: 20%
- Another staff member took or moved the apple: 10%
- The apple was thrown away accidentally: 8%
- Supernatural explanation: 2%
Step 3: Update Credences Based on Further Evidence
As new information becomes available, the teacher should update these credences. For instance:
- If a student is seen eating an apple shortly after the disappearance, increase the credence for “A student took the apple”.
- If the teacher recalls placing the apple in a different spot or finds the apple elsewhere, increase the credence for “The teacher misplaced the apple”.
- If cleaning schedules or other staff activities around the desk are confirmed, adjust the credences for those scenarios.
Step 4: Consider the Rational Basis for Each Explanation
- Rational basis for human actions: Theft, misplacement, and accidents are common and mundane explanations that require no additional assumptions beyond known human behaviors and mistakes.
- Rational basis for supernatural claims: Requires significant assumption that goes beyond established scientific understanding. It should not be favored without compelling, specific evidence.
Conclusion
A rational approach involves:
- Starting with natural explanations that are most likely based on everyday occurrences.
- Using a probabilistic framework to weigh the likelihood of various scenarios.
- Being ready to update beliefs as new evidence comes in, using principles of Bayesian reasoning.
This method ensures that the explanation chosen for the disappearance of the apple is grounded in logic and evidence, minimizing the influence of unlikely or fantastical explanations unless compelling evidence is provided.
Here’s a rational approach for the teacher, incorporating additional explanations and credences:
Candidate Explanations:
- Student Took It: (High Credence – 70%)
- Justification: This remains the most common explanation for a missing object in a classroom with students.
- Additional factors that could increase or decrease this credence (as before):
- Witnessing students near the apple before it vanished (Increase)
- Knowledge of students prone to taking things (Increase)
- Witnessing students take the apple (Increase)
- Student Took It Accidentally: (Medium Credence – 20%)
- Justification: Students might have bumped the apple or put it in their bag unintentionally.
- Additional factors:
- Precarious apple placement (Increase)
- Past incidents of students accidentally taking things (Increase)
- Janitor Took It: (Low Credence – 5%)
- Justification: While possible, it’s less likely than a student taking it.
- Additional factors:
- Knowing the janitor’s usual routine (Increase/Decrease)
- Asking the janitor if they saw or took the apple (Increase/Decrease)
- Animal: (Very Low Credence – 4%)
- Justification: Highly unlikely for an animal like a deer to enter the classroom and take the apple. School security measures and location would further decrease this probability.
- Additional factors:
- Open windows or unusual animal activity near the school (Increase – unlikely but not impossible)
- Ghost: (Extremely Low Credence – 1%)
- Justification: There’s no scientific evidence to support the existence of ghosts. While ghost sightings are interesting, they lack verifiability.
- Additional factors:
- History of reported paranormal activity in the school (Increase – still incredibly low)
Steps for the Teacher:
- Assign Initial Credences: The teacher assigns initial credences based on likelihood. “Student Took It” gets the highest with 70%, while “Ghost” gets the lowest at 1%.
- Gather Information: The teacher actively seeks information through:
- Asking students if they saw anything or took the apple accidentally.
- Talking to the janitor to see if they saw or removed the apple.
- Checking the classroom for the apple in unexpected places.
- Reviewing security footage (if available) for anything unusual.
- Update Credences: Based on the information gathered, the teacher updates their credences. For example, if a student confesses, “Student Took It” credence increases significantly.
- Draw a Conclusion: Considering the updated credences, the teacher arrives at a more informed conclusion. Here, the most likely explanation will likely be one of the top three options (Student, Accidental Student, or Janitor) depending on the gathered information.
This approach encourages the teacher to consider all possibilities rationally. It prioritizes likely explanations while acknowledging highly improbable scenarios like a rogue deer or a ghost. As the teacher gathers more information, their beliefs can be refined, leading to a more well-supported conclusion about the missing apple.
Provide 3 other hypothetical cases in which the high probability that one of many low-probability explanations was irrationally discounted, and another low-probability explanation was asserted.
Certainly, let’s explore three hypothetical scenarios where the collective probability of several low-probability explanations, when combined, outweighs the probability of an irrationally asserted low-probability explanation.
Scenario 1: The Vanishing Vehicle
Context: A family returns from vacation to find their car missing from their locked garage.
Potential Explanations:
- Stolen by a professional thief: 10%
- Borrowed by a relative who forgot to mention it: 5%
- Mistakenly reported as abandoned and towed by the city: 5%
- Repossessed due to a clerical error by the bank: 4%
Combined Probability of Likely Explanations: 24%
Asserted Low-Probability Explanation:
- Car vanished due to a spontaneous dimensional shift (based on a popular science fiction theory): 1%
Analysis: The combined probability of conventional scenarios (theft, family mistake, towing, repossession) significantly outweighs the fantastical idea of a dimensional shift, yet the owner fixates on the sci-fi explanation due to a recent movie they watched.
Scenario 2: The Disappearing Ink
Context: An author finds that the ink on some manuscript pages has inexplicably faded, rendering sections unreadable.
Potential Explanations:
- Ink quality was poor or defective: 20%
- Exposure to sunlight or chemicals that bleached the ink: 15%
- Accidental water damage that diluted the ink: 10%
- Pages swapped with another document by mistake: 5%
Combined Probability of Likely Explanations: 50%
Asserted Low-Probability Explanation:
- Ink faded due to paranormal activity in the house, as suggested by local superstition: 2%
Analysis: Even though each mundane explanation carries a relatively moderate probability, their cumulative likelihood provides a more rational basis compared to the supernatural explanation adopted due to local ghost stories.
Scenario 3: The Phantom Sounds in the Office
Context: Employees in an office building report hearing mysterious tapping sounds that cannot be easily explained.
Potential Explanations:
- HVAC system causing intermittent noises: 15%
- Building settling and causing creaks: 20%
- Minor seismic activity undetectable to humans but causing vibrations: 10%
- Wildlife (e.g., birds or rodents) in the building structure: 25%
Combined Probability of Likely Explanations: 70%
Asserted Low-Probability Explanation:
- The office is haunted by a ghost, based on a legend about the building’s historical use as a mortuary: 5%
Analysis: The rational explanations related to building mechanics and natural occurrences together form a substantial probability. However, employees, influenced by the eerie history and bolstered by a few suggestive experiences, prefer the ghost theory.
Conclusion
In these scenarios, the tendency to favor a more sensational but less probable explanation over more mundane but collectively likely ones illustrates a common cognitive bias known as the neglect of probability. This bias can lead to disregarding the more statistically probable collection of events in favor of a singular, less likely, but more thrilling explanation. It underscores the importance of considering all possible explanations and objectively assessing their probabilities before drawing conclusions.
GEMINI appears confused about the request.
- A Flat Tire on Mars:
- High Probability Explanation (Discounted): Puncture from a sharp rock on the Martian surface. (70% Credibility)
- Low Probability Explanations (Asserted):
- Sign of Alien Technology Malfunction (20% Credibility)
- Evidence of a Previous Martian Civilization (10% Credibility)
Imagine a future scenario where a rover exploring Mars experiences a flat tire. The most likely explanation is a puncture from a sharp rock, a common occurrence on such a terrain. However, the public, fueled by excitement about alien life, might sensationalize the situation. Theories about malfunctioning alien technology or even remnants of a past Martian civilization, despite having lower individual credences, could collectively gain more traction due to their captivating nature.
- Power Outage in a Hospital:
- High Probability Explanations (Discounted): Equipment Failure (50% Credibility), Grid Overload (40% Credibility)
- Low Probability Explanations (Asserted): Targeted Cyberattack (10% Credibility)
A sudden power outage in a hospital creates a tense situation. While equipment failure or grid overload are more likely culprits, some might jump to the conclusion of a targeted cyberattack. This low-probability explanation, fueled by anxieties about cyber warfare, could grab headlines, despite being overshadowed by the combined probability of the more common causes.
- Missing Ship in the Bermuda Triangle:
- High Probability Explanations (Discounted): Severe Weather (40% Credibility), Human Error (30% Credibility), Equipment Failure (20% Credibility)
- Low Probability Explanation (Asserted): Paranormal Activity in the Bermuda Triangle (10% Credibility)
The Bermuda Triangle, infamous for unexplained disappearances, sees another ship vanish. Despite the most likely causes being bad weather, human error, or equipment failure, the mystique surrounding the area might lead some to assert the low-probability explanation of paranormal activity. Even though less probable, the captivating nature of the Bermuda Triangle legend could overshadow the more mundane but statistically more likely explanations.
Take one of ChatGPT’s scenarios and provide a thorough pedagogical explanation why the rationale is flawed.
Scenario 1: The Vanishing Vehicle
Context
A family returns from vacation to find their car missing from their locked garage.
Potential Explanations
- Stolen by a professional thief: 10%
- Borrowed by a relative who forgot to mention it: 5%
- Mistakenly reported as abandoned and towed by the city: 5%
- Repossessed due to a clerical error by the bank: 4%
Combined Probability of Likely Explanations: 24%
Asserted Low-Probability Explanation
- Car vanished due to a spontaneous dimensional shift: 1%
Analysis
The combined probability of conventional scenarios (theft, family mistake, towing, repossession) significantly outweighs the fantastical idea of a dimensional shift, yet the owner fixates on the sci-fi explanation due to a recent movie they watched.
Pedagogical Explanation of the Flawed Rationale
Understanding Probability
The major flaw in the asserted explanation for the disappearance of the vehicle is a fundamental misunderstanding of probability and statistical reasoning. The probability of each conventional scenario is low individually but when considered collectively, they substantially increase the likelihood that the disappearance is due to a mundane reason.
Law of Total Probability
The law of total probability states that the total probability of an event occurring can be found by considering all mutually exclusive ways in which it can occur. In this scenario, the ways the car could have vanished (theft, borrowing, towing, repossession) are not overlapping and together form a more comprehensive explanation. The mathematical formulation would be:
[ P(\text{Car Missing}) = P(\text{Theft}) + P(\text{Borrowed}) + P(\text{Towed}) + P(\text{Repossessed}) ]
Thus:
[ P(\text{Car Missing}) = 10\% + 5\% + 5\% + 4\% = 24\% ]
Dismissing High Probability Events
By focusing on a dimensional shift—an event with a 1% probability based on speculative fiction rather than empirical evidence—the owner irrationally dismisses more probable and mundane explanations. This is an example of the psychological bias known as the availability heuristic, where individuals overestimate the importance of information that is more readily available to them (in this case, influenced by recent science fiction media).
Bayes’ Theorem and Updating Beliefs
Rational thinking would require updating beliefs based on evidence using Bayes’ Theorem:
[ P(H|E) = \frac{P(E|H) \times P(H)}{P(E)} ]
Where:
- ( H ) is the hypothesis (e.g., the car was stolen).
- ( E ) is new evidence (e.g., the car is missing).
- ( P(H|E) ) is the probability of the hypothesis given the evidence.
Without specific evidence supporting the dimensional shift, its probability remains low compared to other hypotheses.
Practical Implications
Believing in the low-probability explanation without empirical evidence can lead to inappropriate actions or lack of action:
- Failure to Investigate: Dismissing high-probability scenarios might prevent the owner from taking practical steps like checking with relatives, contacting the police, or verifying with the bank or city towing records.
- Resource Misallocation: Resources might be wasted on seeking unlikely explanations (e.g., consulting fiction-based theories) rather than addressing plausible causes.
Conclusion
The pedagogical takeaway is the importance of applying rational, probabilistic reasoning to everyday problems. Understanding how to aggregate probabilities of independent, non-mutually exclusive events and using appropriate statistical reasoning (like Bayes’ Theorem for updating beliefs) is crucial in making informed decisions. This scenario underscores the need for skepticism and empirical validation when confronting unusual or unexpected situations. This approach prevents the fallacy of favoring sensational but implausible explanations over more probable mundane ones.
The Flawed Allure of the Improbable: Analyzing Scenario 1 – The Vanishing Vehicle
Let’s dissect the flawed reasoning in Scenario 1: The Vanishing Vehicle. Here’s why the owner’s fixation on the “dimensional shift” theory is illogical:
- Probability vs. Possibility: While the sci-fi explanation (1%) is technically possible, it’s incredibly improbable. There’s no scientific evidence to support spontaneous dimensional shifts in everyday life. The combined probability of the listed conventional scenarios (24%) is significantly higher, making them far more likely explanations.
- Occam’s Razor: This principle of parsimony suggests that in the absence of compelling evidence, the simplest explanation is usually the most likely. Stealing, borrowing, mistaken towing, or repossession are all well-understood phenomena with established patterns, making them far simpler explanations than a dimensional shift requiring exotic physics.
- Confirmation Bias: The owner might be experiencing confirmation bias. Their recent exposure to the sci-fi movie might make them subconsciously seek out evidence to fit that narrative. They might misinterpret details (e.g., no signs of forced entry) to support the dimensional shift theory, overlooking simpler explanations.
- Lack of Evidence: The sci-fi explanation lacks any supporting evidence. There’s no indication of futuristic technology or displaced objects, unlike the potential evidence associated with the conventional explanations (e.g., broken window for theft, witness for borrowing).
Here’s a more logical approach:
- Gather Information: The owner should first investigate the more likely scenarios. This might involve checking with relatives, contacting the police or towing company, and verifying details with the bank.
- Evaluate Evidence: Any evidence found (e.g., security camera footage, witness accounts) should be used to refine the possibilities.
- Seek Expert Opinion: If no clear explanation emerges, consulting a mechanic or law enforcement might be necessary.
By focusing on evidence-based explanations and employing a systematic approach, the owner can arrive at a more rational conclusion than resorting to a highly improbable sci-fi scenario.
