Hello, I am very inspired by your methods. Unfortunately, I am not as smart as you and can deduce without any practice. But you must have developed your ‘deduction skills’ over the years too… it requires a lot of knowledge, does it not? Anyway, getting to the point. To get better at something, not only practice but also feedback ist required. Do you know any sort of ‘game’ or anything to practice deduction? (You know what I mean!) I know the subreddit r/scienceofdeduction which can be helpful sometimes but that depends on the people who upload there. I thought of a game in which you get an item from anyone you’re playing with (you don’t know from whom) and you have to deduce whose it is. Problem is that I don’t have friends/ know ppl who’d do this with me. So any suggestions?
(Disclaimer: English isn’t my first language/ mother tongue/ however you say it)
Of course I had to develop and hone my deduction skills over the years. Even as a child, I already had a certain tendency to know things that other people didn't, but that is probably a family thing, as my siblings were even better at it. To improve my skills I did have to practice, and I learned much from my older brother with deduction games. Everyone has to start at some point and practice to improve. Of course some people are naturally gifted, but even they have to put work into their skills to further improve. Deducing people based on objects is a good exercise, but maybe you could modify your game idea. Change the game so you do not find the person who it belongs to, but just receive the object itself or a picture of the object and then you have to make deductions about the person based on the object, but not knowing who they are. A deduction game I could suggest is to deduce someone based on a picture they sent you. Like of their desk, of their room, or a screenshot of their phone screen. I think there are some online groups like you mentioned where people provide such pictures, but be careful to not reveal too much about yourself. Another possible training ground could be Tumblr, going through people's blogs and deducing them based on what they post. Going outside and watching people pass by on the street or public transport, deducing them based on what you see, their clothes, their behaviour, et cetera. But sadly you will not be able to find out whether your deductions are correct, except if you walk up to people and ask them. But that does not turn out good in most of the cases, trust me. Maybe Youtube has some useful deduction games and exercises as well.
It is not only important to train your deductions, but also to train your observation and memory. Practice to think fast, make quick observations. Look at a picture for 20 seconds, memorise it, and then try to recount everything you saw. Build yourself a mind palace to be able to store information better, visualise things.
There are endless possibilities of practice, and you can create your own games as well. Me and some followers played some deduction games about a fictional crime case, by asking 20 questions and trying to solve the case just based on that. Maybe you could also participate the next time. Good luck with your deduction journey then.
