At a freshman event to welcome new students to campus, an "expert" offers to read palms and give predictions about the future. The routine is very authentic-looking and entertaining, but there is no evidence that these predictions are anything more than guesses.
Palmistry, therefore is an example of
A. Experimenter bias
B. the third-variable problem
C. a pseudoscience
D. a double-blind situation
(I got C incorrect)
