Only 120 IQ here, solving complex puzzles is not my bag but I have a good instinct and a sixth sense. People with high IQ however suffer from overthinking things sometimes and being too hung up on how smart they are, they are often completely wrong because they can't think outside their own box.
The best thing high IQ people can do is to not rely on their emotions mistaking it for gut instinct or intelligence, these things get mixed up sometimes. Intelligence can work out solutions and instinct can guide but emotions very often betray these things.
That's the problem with most intelligent leftists, they think what their emotions want is the truth because they are smart but they aren't listening to their smarts at all.
Discipline and experience can help but the problem is smart people are sometimes so in love with their intelligence they often think what they feel is smart.
