Which is harder to memorize instantly: a series of numbers or letters?
Numbers. Numbers have very close relationships. Letters are less complicated because they have a sound that’s associated with them and sink in your brain without having a ton of connections to it. It’s why it’s easier to talk than type in binary code to express a sentence. If you think of the letters FNTUH versus the numbers 28394, the letters stick out from one another. You might mix up the stuff in the middle, but the numbers will get all chopped up and you wont remember possibly how many numbers there were altogether. I used to practice remembering up to 18 numbers while only looking at the numbers in a row for about half a minute. I started with numbers like 1231 and 879, and eventually got up to 1239819238091231298 after about 6 months. It’s possible, but letters are easier. Your brain has clear connections made with letters, and they dont seem to blend together into one giant confetti mix. If you think about it, that’s why we need to use commas for every three digits in numbers l
