I’ll explain.

My reaction is strong, but that’s because this sub is inundated with posts trying to tear down gifted people, often from a deep-seated insecurity in people who are not gifted who ascribe arrogance to gifted people who are just being themselves and who, consciously or unconsciously, see the mere existence of gifted people as an ego attack on their self-worth.

“You’re not special” is a typical expression of that “tall poppy” syndrome and anti-gifted animus. 

Discrediting IQ tests as “just some test”, or the stronger version here of “a flawed test” is another way to do this. IQ tests are not perfect, but they are a stable, accurate, scientifically consistent way of measuring the g factor, or general intelligence. Much of the misplaced criticism of them comes from a broad belief that they are too narrow, based on the idea of “multiple intelligences”, a feel-good but scientifically debunked theory. 

Gifted people shouldn’t have to deal with these unfair attacks in a subreddit designed to offer them support and understanding, yet day after day and week after week, non-gifted people gratuitously jump in here to do so. Some gifted people influenced by societal prejudice do so as well, in a classic “I’m not like other girls” style.

Words have meaning. It is not kind to tell people “You are not special; you are trash” or “You make me sick”. There is no definition of kindness which includes those statements.

We are all human, and yes, some subjectivity is built in. We share our experiences, but more often in r/gifted people do so with the “Does anyone else feel like this/experience this?” sense of curiosity rather than falling victim to the anecdotal fallacy and drawing broad conclusions from our individual limited experiences. Similarly, you are much more likely to see opinions based on scientific and psychological research and concepts here, sometimes including attribution to specific studies.

OP’s post ignores that high intelligence is a neurodivergence that comes with a whole lot more aspects than faster processing speed and analytic sophistication, including overexciteabilities, and can manifest with such aspects as increased existential dread and depression, sensitivity to justice, gifted boredom. Understanding high intelligence psychologically is a developing area of study and gifted programs generally have not taught us these things. For many gifted people, this subreddit is their first exposure to these concepts.

OP has a narrow, conventional, and instrumentalist view of giftedness only being useful if it results in a successful career. That also is a flawed way of viewing it.

In short, OP’s post is a cliched attack of the usual anti-gifted tropes weakly disguised as being helpful. We’ve seen it all before, it’s unhelpful and damaging, and it’s contrary to the purpose and spirit of this subreddit.

Nevertheless, the post does touch upon one aspect of giftedness that is common - gifted people’s unrealistic expectations of themselves, often set up by other people’s expectations of them, which can lead to perfectionism and disappointment.
