I understand how you feel.
I too went through a stage of having to dumb down my vocabulary as many people thought I was trying to show superiority over them.
I am no intellect, I just enjoyed reading dictionaries and doing crossword puzzles. So there are many words in my head.
I eventually decided not to simplify my vocab.
Just yesterday a person thanked me because they learned a new word which I had used. Perambulation

Dumbing down is a valid concept, but it’s a fool’s errand. The gift in life is learning from everyone. There’s just so much to learn. IQ doesn’t measure, for example, potential or desire. It certainly doesn’t measure success either. It’s simply a flawed yardstick, as:

There’s always a kinder perspective.
There’s always a better athlete.
There’s always someone smarter.
The empath feels more.
The flirt is more socially adept…

Some see the best path while others see the roses along the way.

It doesn’t matter how many standard deviations you are from the average because you’ve never described a friend or companion as ‘average’. The adjectives used would always be about what makes them special.

Ergo, the gift isn’t IQ. It’s leveraging it to be fulfilled. For that, you need others. They’re THE key ingredient. They’re the key to happiness.

Plus, the real measure in life isn’t IQ. It’s love, and that’s shareable.

I know the feeling. Tested 3 times..........member of MENSA. IQ....151...... all 3 times.

This site attracts intelligent people, even though they don’t always show it!

I would suggest to not take pride over your iq, as you are still relying on 2nd hand information of books written by someone in the past. Encyclopedia is for reference and not knowledge. Intellect is in how you interpret what you read as otherwise it contributes to blind beliefs .. Your iq can become your firewall preventing truth to reach you.

Don't hide your brains, be proud of them -- just don't treat other people as inferior.

Don't dumb yourself down.
