"Fig. 3. Performance on conjunction tasks and base-rate task, before and after training."
"Participants (N = 56) were randomly assigned to a training group, which completed a series of conjunction judgment tasks with feedback, or a control group. Results showed that the training group improved on both trained and untrained conjunction tasks, including those based on real-world and clinical scenarios, while the control group showed no such improvement. No transfer effects were observed for unrelated base-rate tasks. Performance gains were gradual, suggesting that participants developed judgment strategies over time rather than immediately adopting normative rules. These findings demonstrate that conjunction fallacies can be mitigated through self-guided learning with minimal instruction, offering a promising approach to improving probabilistic reasoning."
"Training stimuli consisted of 30 judgment problems. A variety of tasks were used to keep participants attentive and ensure they read through the full task description. The training set comprised 15 Lindalike conjunction tasks from Andersson et al. (2020), six conjunction tasks comprising fictional situations paraphrased from the research literature, three conjunction tasks describing sequences of dice rolls (Tversky & Kahneman, 1983), and three conjunction tasks describing sequences of letters (Tversky & Kahneman, 1983).
Further, we included three Monty Hall tasks..."
"The control group instead completed 30 spelling tasks."
"Each block of decision tasks comprised 12 (pre- and post-test) or 10 (training) tasks in randomized order, which were completed one by one. As described under materials, a task included a brief description, a question or prompt, and the choice alternatives. This text was presented together with an image relating to the description in the task (Fig. 1A). There was no time limit on any task, and the task concluded once a choice was made by clicking on an alternative.
Participants in both the training and control groups were informed about correct or incorrect responses after each trial, but no further feedback on which strategy to use."
Can feedback on #cognitiveBias tests train people to overcome #bias?
56 people were randomized to practice either 30 cog bias tests or 30 spelling tests between 12 pre- and post-tests (about news, clinical psych, etc.). Decision practice/feedback helped!
