📜 Intellectual Property
This test is an independent educational adaptation inspired by scientific research in cognitive psychology, notably the Comprehensive Assessment of Rational Thinking (CART) developed by Keith E. Stanovich, Richard F. West, and Maggie E. Toplak, published by MIT Press in 2016.
⚠️ Important Disclaimer
This project is NOT the official CART and is not affiliated with MIT Press, Keith Stanovich, Richard West, Maggie Toplak, or any academic institution associated with the development of the original CART.
🎯 Usage and Purpose
This project is provided for free, as open source, and for strictly educational purposes. It should not be used for commercial purposes, clinical diagnosis, or professional decision-making (recruitment, career guidance, etc.).
- Educational purpose only
- Not for clinical diagnosis
- Not for commercial use
- No affiliation with original CART authors
🔬 Methodology and Sources
This test uses:
- Public domain questions from scientific literature in cognitive psychology
- Original variants inspired by peer-reviewed published research
- Adaptations of classic reasoning problems (CRT, conjunction fallacy, base rate neglect, etc.)
🔄 Differences from Official CART
This adaptation differs from the original CART in several aspects:
- Shorter format (20-90 minutes vs. 3+ hours for full CART)
- Unsupervised online administration (vs. controlled administration for CART)
- Adapted and translated questions (vs. standardized CART questions)
- Indicative norms based on theoretical distribution (vs. validated psychometric norms of CART)
