Well, there's a broader effect based on an availability heuristic, where people accept explanations that come easily to mind even (as in this case) where the reasons for their availability are not actually related to their truth. So you could consider this a special case of availability bias.

Though that is admittedly a very broad category, possibly uselessly so.

The problem with the availability heuristic is that once I get used to using it as an explanation, it comes more easily to mind, so I am more likely to accept explanations involving it.
