The only thing I question about IQ is often these journalists and the intelligentsia claim to have a high IQ as one of the reasons we should listen to them. Yet, they are idiots. So, is the metric broken, are they lying about their IQ, or do they really have a high IQ and are just manipulating us?

There's no doubt general intelligence is on the decline. Outside of dumbing down the gene pool, I think of what is left, a lot of it stems from a lack of learning to apply intelligence though. My cousin is like this, he's intelligent, I can tell he's intelligent, but he has zero patience to seek a solution. If the problem is not solved in five minutes by the first thing he tries, usually being at best the first search result he finds, he's done with it. Every time I've pushed him to slow down, use his head, and actually think how things work and how to solve the problem on his own, he figures it out. It's a product of the phone generation, everything is just presented to them. They don't ever stop and think.
