© 2018 Wojciechowski and Pothos. Is There a Conjunction Fallacy in Legal Probabilistic Making? by Wojciechowski, B. W., and Pothos, E. M. (2018). Front. Psychol. 9:391. doi: 10.3389/fpsyg.2018.00391 In the original article, there was an error. In the Discussion section, a small error was made in one of the quantum computations, which requires minor adjustment of the discussion. None of the empirical results, analyses, and other conclusions are affected. A correction has been made to Discussion, paragraph 7. The original sentence was: For a double CF, we have: Prob(A), Prob(B) > Prob(A & B), that is a CF occurs for both conjuncts. This has been corrected to: For a double CF, we have: Prob(A), Prob(B) Prob(A & B), for when evaluating criminal cases for which the suspect was guilty for both crimes. This has been corrected to: For the participants with no legal background, we have a situation where Prob(A), Prob(B) < Prob(A & B), for when evaluating criminal cases for which the suspect was guilty for both crimes.
