I've met people who are highly intelligent, and often they place the intelligence of people on a hightened level, as if the value of higher intelligence is what matters more than most other things in regards to people...
Sometimes, they will even admit that they don't like wasting their time speaking to or listening to those they deem less intelligent than them...
Other times, I fear what would happen if the world were filled with highly intelligent people.
...What is your opinion of those who write-off the less intelligent? Is it justifiable in your opinion? Why do they do it..?
I think it is a simple factor of the Bell curve, there being far fewer highly intelligent people, and it does tend to isolate one more than most, and especially where one might recognise better answers coming from other intelligent people but often ignored by the majority, within which one must live. Hence the nature alone tends to isolate one, even in a democracy, but where many probably will not be voting for those things most thought about but rather on just what affects them. That's just one example why they might be alienated from others - the others always being in a majority.
Also, many highly intelligent people might be using the rational part of their brain much of the time rather than the intuitive part (or more emotional part), and hence might come across as less feeling.
I've met some highly intelligent people, and most to me didn't have the arrogance which is cited here. I think perhaps they would rather be conversing with others of similar intelligence, and have a chance of further learning, than not doing so, unless they enjoyed showing off their intelligence and possibly dominating others. Not met so many of them either, and they are easily spotted.
I'm sure it can be quite lonely being so highly intelligent, and fortunately I am not such, but I am sufficiently intelligent to understand how it might feel. I also think that anyone with sufficient intelligence is unlikely to place intelligence as having a higher value than many other qualities, especially when we see what such often brings to life. A few might, but not a majority.
And no, highly intelligent people are as just as likely to be cruel as any others.
