Anyone know of any videos or youtube channels where they teach you techniques for making different deductions? I'm thinking more along the lines of specific tips like "how to read someone's clothes/appearance for their occupation" or smaller little tips like "how to tell whether someone is left/right-handed" or "how to tell how long a car has been parked somewhere" rather than big "how to expand your mind" type stuff.
No idea about videos, but there exist a very pleasant card game called " Black stories" (different editions, from medieval to musical) where you have to solve lots of exceptional murders. Quite a fun!
