Science vs Pseudo-Science
For something to be scientific it needs to be 2 things
- logically consistent
- if it rains, the floor gets wet
- needs to be falsifiable
- theory: all swans are white
- how to falsify: find a non-white swan
- if I can’t find a white swan
- “I cannot falsify the theory yet”
- but the theory is not proven
Errors
Type I - false positive (alpha)
- the prisoner is found guilty, but is innocent
- standard is 5% as a scientific community
Type II - false negative (beta)
- the prisoner is not found guilty, but has committed the crime
- … = power of a test
- not relevant, but for future studies
- no definite decision, no yes/no
- just a rather/rather not
