Understanding Logical Fallacies to Identify Flawed Arguments
Common logical fallacies include ad hominem, strawman misrepresentations, and appeals to authority in arguments.
Factually incorrect
The exact change
Before
Wason's follow-up research showed that the error rate dropped to 65-75 percent correct when the rule involved someone drinking beer and being over 21.
After
Later research by Griggs and Cox (1982), not Wason himself, showed the error rate dropped to roughly 70-75 percent correct with the same social-context rule, using the real study's drinking age of 19.
Why this is better
Verified the Wason selection task and the beer/drinking-age variant against the actual research literature; the social-context version is a separate, later study by different researchers, not a Wason follow-up.
