Over the years I've done like eighty billion twitter polls and also a metric poopton of surveys with huge Ns where i stare at correlations a ton. I've developed my own personal intuition for correlation strengths; idk if it's "scientific" but the way I tend to look at things:

My rough threshhold for "this is kinda interesting" is around r=0.12. "ok i'm paying attention" starts at around r=0.18, and "i'm getting excited" starts at 0.22. Anything 0.3 and up gets first-time-watching-lord-of-the-rings level feelings of magic and r=0.5s mean i am deceased

r=0.7s and up are mythological creatures no one has ever seen one, and if u think u saw one it probably was just some dude in a suit made out of a pitiful sample size

yeah hugely dependent on the subject i think! For example, height and weight is correlated at around r=0.5.

As an extreme example, they don't bother doing statistics for high-school level Newtonian mechanics, because if you're measuring acceleration versus force your r should be 0.99 and what do you even mean by a p-value.
