They’re related. Some argue that confirmation bias is an example of belief overkill. Belief overkill is basically the tendency for people to accept all arguments that support their opinion even if it is only in a peripheral fashion. Thus, for example, people who think that using fetal stem cells for medical purposes are moral are much more likely to think that stem cells will be really medically helpful than people who think that such use is bad. Essentially, people compile arguments for why X is Good/Bad rather than dividing questions properly. There are some posts that touch on this issue (such as those discussing why politics is a mind-killer) but I’m not aware of any post discussing this issue in detail (although given how extensive the archives are I estimate a high probability that I’ve simply missed the relevant ones).
Motivated cognition would also be a special case of belief overkill—it’s being too ready to develop and accept arguments what you want to believe. Belief overkill is the same process applied to arguments from both yourself and other people.
Is belief overkill different from confirmation bias (which is what comes up when I google)?

Sounds a lot like the halo effect.
Policy Debates Should Not Appear One-Sided is related to belief overkill, I’d say.
