I have lived this in contexts, it is absolutely true. Energetic dumb people get noticed and often promoted based on their energy and seeming ability to move fast. That quickness is usually due to the fact that they don’t do any proper due diligence or analysis, they just bull ahead.

The trick is to catch them early enough and get rid of them as quick as you can.

Seen this both in startups and big companies where a person was fired a year to the day they were hired (or whatever their contractual “safe period” was).

I have also seen orgs where they did not catch them in time. You do not want to work there.
