I've experienced this so profound changes in my cognitive ability in my own life, but interestingly they don't seem to show up in IQ tests I've taken. My IQ today in my mid 30s is about the same as what it was when I was 16. However there's not doubt in my mind that I'm far less creative, far slower to reason and far slower to grasp concepts today than in my early 20s. In some ways I notice I'm smarter in the sense that these days I have more knowledge to fall back on so I wonder if this biases my IQ score a bit. For example, when I take IQ tests I often recognise patterns like the fibonacci sequence which I wouldn't have been familiar with in my teens. In many ways I'm a more capable human, but specifically for tasks requiring creativity and adaptability, I'm far less able than I was in the past. I'm an amateur musician and throughout my teens and early 20s I enjoyed writing music. I still do enjoy writing music but I've noticed in recent years I seem to lack the creativity to write anything I care for. I think this is partly that I have too much experience which biases my creativity and I fail to do anything interesting because I fall into familiar patterns. But even in areas where I have less experience I seem to struggle to be as creative as I once was. I guess the only way I can describe it is that it's like that intellectual rebelliousness I once had is not there anymore. Startups are also harder today because I find I'm slower to adapt to modern approaches and lack creativity in similar ways I do in music. It's depressing as hell. I wish I could extract my knowledge and have my stupid old creative brain back. At least then I could do interesting stuff. Sharing because I don't know if anyone here relates. I'm only in my 30s too so if this is the trend I'd hate to think how uncreative and boring I'll be as I get older.
