Frequency Illusion

Let’s say you learn that Asmara is the capital of Eritrea.
A week ago, you didn’t even know there was an African country named Eritrea. 

Now every Uber driver you meet happens to be from…you guessed it, Eritrea.
This is a strange phenomenon related to memory—and it’s called the Frequency Illusion.

Now that you know about X, is X starting to show up everywhere or was X always there
and you’ve just become attuned to noticing it?

That is the million-dollar question, as it turns out.
I bet someone will mention Frequency Illusion to you.
