A place to discuss potentially promising methods of intelligence amplification in the broad sense of general methods, tools, diets, regimens, or substances that boost cognition (memory, creativity, focus, etc.): anything from SuperMemo to Piracetam to regular exercise to eating lots of animal fat to binaural beats, whether it works or not. Where's the highest expected value? What's easiest to make part of your daily routine? Hopefully discussion here will lead to concise top level posts describing what works for a more self-improvement-savvy Less Wrong.
Lists of potential interventions are great, but even better would be a thorough analysis of a single intervention: costs, benefits, ease, et cetera. This way the comment threads will be more structured and organized. Less Wrong is pretty confused about IA, so even if you're not an expert, a quick analysis or link to a metastudy about e.g. exercise could be very helpful.

Given how important o-3 is to cell membranes (even if o-3 did not reduce inflammation) and how important cell membranes probably are to brain function, reducing -6 intake is unlikely to have a strong cognitive benefit. According the my amateurish models, the most important way keeping o-6 intake low impacts cognition for a young guy like you is by slowing the rate at which your brain will deteriorate over the decades. In other words, the inflammation reduction is caused by a reduction in prostaglandins, which are synthesized from fatty acids, where prostaglandins have no particular role that I know of in the maintenance of cell membranes -- they're paracrine hormones.
