I’ve dealt with hundreds of customers with strong personalities, and one thing I’ve noticed is that people below them may have good ideas, but when confronted with pushback from a strong personality they drop the whole thing. Most employees can’t stand up to a huge level of scrutiny.
Strong personalities tend to come from decisiveness, making a decision about a belief one time and being done with it.
“The test of a first-rate intelligence is the ability to hold two opposed ideas in mind at the same time and still retain the ability to function.”
F. Scott Fitzgerald
As F. Scott Fitzgerald notes, intelligence is correlated with the ability hold two opposed ideas. That means giving a new idea equal weight to a held belief until it can be determined which is correct. Most people don’t operate this way. They hold on tightly to their first belief. That’s why nefarious marketers target children. Getting children to believe smoking is cool for instance, means it takes significantly more effort to get them to change that belief than it did to create it.
Intelligence is throwing out the bad data, and replacing it with better stuff, however, you’ll never see the better ideas, if you’re stuck firmly to the old ones and scrutinizing anyone who offers something else.
