I think the core issue is that everyone reacts differently to different approaches of conveying a problem. Some people you scream at them "You're trash, you suck!" and their motivation to succeed explodes. Do it to others and they just collapse and check out. Some people screw up big, get a gentle talking to, and walk away feeling like it's no big deal. Others are dead inside and know they can never make that mistake again.

There is no magic response, it needs to be tailored to the individual, and being able to read what kind of response is right for which individual is part of what separates shitty and great managers.
