Wait until you find out that the Ars Memoriae or 'Art of Memory' was highly developed and taught as a liberal art well into the 17th century, often integrated into the Trivium.
It's a shame we don't read Latin anymore, as it grants access to our rich intellectual patrimony.
Dave Asprey claims you can boost your IQ by around 12 points in a month with one specific brain training method.
On The Iced Coffee Hour, he described dual n-back training: a frustrating grid game where you track both the position and the symbol from several moves back. Just 20 minutes a day. Most people quit, but sticking with it for ~20 sessions can dramatically improve working memory (e.g., going from remembering 7–8 items to 16).
Dual n-back training reliably improves performance on the trained task and can enhance working memory capacity. Some studies show modest transfer to fluid intelligence (problem-solving aspect of IQ), but results are mixed, meta-analyses find small average gains (often 2–5 points) that are stronger in lower-quality studies and don’t always hold up in well-controlled trials.
The idea that you can deliberately train a core cognitive skill like working memory is intriguing, even if the IQ boost isn’t guaranteed to be that large.
In a world full of distractions that shrink our attention, a simple daily practice that strengthens your brain’s ability to hold and manipulate information could be genuinely useful.
Would you commit to 20 minutes of frustrating brain training every day for a month if it could meaningfully improve your focus and memory?
