What is a case study?
- Business ideas
- Analyzing competing solutions
- Exploit the topic → pros and cons
- Story to illustrate a concept
Main key points for a battle
- Achiving generalization starting from particular scenarios
Example:
Telling general law starting from a large number of examples
- Wrong generalization
- Impossible to generalize because of:
- The past may not reflect the future
- Not enough data points - even though it might cover all the cases, it might not have enough data points to make a conclusion on those who are most common or not
- Wrong dataset - it may not cover all the cases or be biased
- Unknowingly partial dataset - sometimes we don’t know that our dataset is partial because we don’t have knowledge about the full range of possible data points.
Example:
A case when induction is not applicable: “A farmer feeds a turkey every day at 8 am in any weather conditions, without failing. On a given day, the turkey is expecting to be fed but the farmer got there and kill it for thanksgiving” Karl Popper.
- Having a general law and deducting specific cases
Scientific method is falsificatory because it does not prove that some law is true. You’re trying to find situations where the law does not apply.
- The past may not reflect the future
- When people are sure about a thing they will continue to search for arguments that support their theory and not arguments against
Quote:
It is a capital mistake to theorize before one has data. Inevitably, one begins to twist facts to suit theories, instead of theories to suit facts.
- Sherlock Holmes (2009 film)
Example:
The flat-earth theory
Example:
Conspiracy theories
