Google Dunning-Kreuger effect. That ‘splains it.
You gotta wonder why people don’t tell them. But you gotta also wonder why they can’t hear it themselves? You know... I’m a pretty good musician. Have played in a lot of bands over the many years. But I’m not a very good singer.... I mean at least I know it... and I can hear it. I’ve met dozens of people over the years who were horrible singers... and convinced they ROCKED... I’ve never understood that.
