"Observer effects are rooted in the universal human tendency to interpret data in a manner consistent with one?s expectations. This tendency is particularly likely to distort the results of a scientific test when the underlying data are ambiguous and the scientist is exposed to domain-irrelevant information that engages emotions or desires"
Isn't that just the cat's meow?
I'm a social scientist so I understand that. But that observation does mean that EVERY observation is wrong, does it?
