The low overall score reflects that 'Thinking, Fast and Slow' is a renowned psychology book summarizing decades of research on cognitive biases and decision-making (System 1 fast/intuitive vs. System 2 slow/deliberative), but it contains no ingredients for supplement analysis. Effectiveness is 0 due to absence of clinical evidence for health claims via RCTs or meta-analyses on Examine.com or PubMed—no dosages or supplement studies exist. Safety is maximal at 100 with zero risks from reading. Qua
This is an outstanding book on cognitive psychology backed by rigorous research, but it is not a supplement and scores poorly under supplement analysis criteria. Recommended for personal development, not health supplementation. Seek actual nootropics if desiring cognitive enhancement products.
