in fact, you have to do this often. if you want to change someone’s behaviour, telling them what they’re doing wrong is less effective than reinforcing what they’re doing right.
if you’re constantly berating an individual for every mistake they make, this individual is going to become conditioned into thinking EVERYTHING they do is wrong. and they’ll then become scared to make a mistake, thus ensuing they make more mistakes.
humans need praise. if you see something that someone has done well, tell them. this is in fact much more important than notifying them of their mistakes. if you listen to the greatest coaches of all time and you dissect their communication, you’ll find that only 6.6% of their communication is criticism. it’s information, not criticism, that will get the most out of your employees and players.
humans aren’t stupid. they know when they’ve fucked up; they don’t need you to tell them. but often people struggle to see their strengths, to see their successes, and that? that’s what you need to tell them. be the kind of person that builds people up, not breaks them down.
