Other peoples Looks and intelligence matter greatly to
Me

Sometimes you're limited by the lack of comprehension of other people - or their lack of comprehension on a particular subject or what you're trying to accomplish. They likely don't have all the information in front of them nor at particular times will they shut the fuck up long enough for you to explain it to them so they can actually understand just WHY X-Y-Z etc means whatever.

It makes them actually pretty dangerous to have and be around. There's just no point. It just fosters corrosive emotions which ultimately distract from if not taint your view of your worth, capabilities, and possible aspirations.

Intelligence is malleable. The Stamford Experiment springs to mind [and I would refer to certain styles of 'parenting' as the same thing as this experiment; same effects caused/experienced]. Prolonged doubt can be very corrosive towards confidence in one's abilities and mental health. It's best kept to the absolute minimum outside of one's natural insecurities.

There are certain things that require time and energy which is ultimately better spent focusing on and working on tasks going toward end goals - if not simple survival and function. I guess intelligence is probably relative in some cases - unless we are referring to a genuinely brilliant mind - but even brilliance can be stifled, since intelligence is malleable. It can be a very delicate thing. It can be compromised, if not broken.

So, other people's intelligence shouldn't matter...but the scary thing is: Yes. it very much matters - much more than would be preferable. Just take a look at racism and church & state/gay marriage etc...

Mostly when I deal with them.

But sometimes I get concerned about people intelligence and their decisions, behaviors, actions as human race.
Specially of leaders... 😐

It does when they are people I interact with. And not for disparaging way. But in a way they helps me communicate the idea to them in a meaningful way.

It matters as far as my decision to listen to what they have to say or whether I find them interesting.

No, only my own.

Not unless it somehow affects me

Only during an election.

The intelligence of others never matters when you are the smartest.

Somwtimes yes

Yes, always
