Watson selection task
The Wason selection task (or four-card problem) is a logic puzzle devised by Peter Cathcart Wason in 1966. It is one of the most famous tasks in the study of deductive reasoning. An example of the puzzle is:
You are shown a set of four cards placed on a table, each of which has a number on one side and a colored patch on the other side. The visible faces of the cards show 3, 8, red and brown. Which card(s) must you turn over in order to test the truth of the proposition that if a card shows an even number on one face, then its opposite face is red?
A response that identifies a card that need not be inverted, or that fails to identify a card that needs to be inverted, is incorrect. The original task dealt with numbers (even, odd) and letters (vowels, consonants).
The importance of the experiment is not in justifying one answer of the ambiguous problem, but in demonstrating the inconsistency of applying the logical rules by the people when the problem is set in two different contexts but with very similar connection between the facts.

Performance U. Fitness Continuing Education | Why Smart Trainers Believe Stupid Things (Part 1): Bias Toward Positive Evidence
I recently did a facebook post, which stated, “Topics such as spinal rehabilitation and biomechanics have such grey areas and so much conflicting information that we really don’t “know” anything! For example, research has continually failed to show how postural, structural or bio-mechanical factors are linked (if at all) to pain and dysfunction, or if ”compensations” are simply a normal variation in human function. Not to mention, we still have no idea (based on research evidence) as to what causes things like non-specific back pain, or what’s the “best” approach to avoid it and treat it, except for, “if it hurts, don’t do it.
