>>12678888The only scientifically proven way to improve your every day logic (and get far transfer) is by improving your relational framing abilities.
This is covered under relational frame theory, which is a psychological theory of human language. It posits that language and higher cognition are closely related.
There is a site called
raiseyouriq.com that gives you the training that they actually used in their studies to improve the cognitive abilities of people ranging from children with disabilities to adults. There is a way to get around paying for it.
Although the site is called "raiseyouriq", they don't actually give any IQ style tests or exercises to train. They are really training your relational framing abilities, which RFT says underlies most, if not all, higher order cognitive abilities. Those abilities just so happen to correlate greatly with IQ scores. Basically the site is named as is for marketing purposes.
Although I was skeptical, I tried it out for a few months as they recommended. I took the same style of IQ test as a pre and post assessment from the same site. This was to give a fair comparison as using differently-styled tests and/or tests from different creators can cause drastically different results even when taken right after the other.
It was the only "cognitive training" I was doing at the time, so I wasn't worried about any interference.
Lo and behold, I actually gained IQ points, to the point where it was statistically significant.
That's my story.
As far as I know, improving relational framing is the only scientifically backed way of improving general intelligence.
