This has me down a rabbit-hole because I'm now trying to find the name for a related concept: once you've learned a new idea/model, you start to notice how it applies to everything around you. I find this happening most often with algebraic ideas but the article you linked alludes to the fact that you're liable to notice this effect at play more in the days after reading about it. I want to call it overfitting but that's not quite right.
What really gives me the goose bumps is if you're, say, listening to a recording of a lecture while looking out the window watching a leaf tumble through the wind - and then the professor uses a leaf blowing in the wind analogy. It's not something you do very frequently; watch and listen to two independent events.
Not only does it stand out, at times it seems to appear more frequent. I found out that was called the Baader-Meinhof Phenomenon.
I suspect they're a form of confirmation bias, however, because it's not easy to remember that you heard about an idea or term you're unfamiliar with. On the other hand, something you've just recently heard or learned stands out: it reinforces the lesson you've just learned.
