What is The Deductivist?
Most people look. Holmes observed. There's a difference. The Deductivist is a weekly newsletter teaching the exact observation and deduction techniques used by Sherlock Holmes — grounded in behavioural science, applied to everyday life. Every issue: one technique, the science behind it, a real case study, and one exercise you can try the same day. Start with the free guide: 25 things your shoes reveal about you. It takes 10 minutes to read. You will never look at people the same way again.
