The “selection effect” is the name for this effect, viewed very broadly. (That is, there is some process selecting what evidence you see, and you reason as if the evidence you saw was not filtered by that process.)
I’m not aware of a more specific name for the “have you ever noticed that my enemies are mean to me, and my friends are nice to me?” effect besides the standard ingroup / outgroup observations (plus the fundamental attribution error).
