Yes, your level of confidence in an issue should be proportional to the amount of effort you've put into understanding it and inversely proportional to uncontroversial metrics of how complex the issue is. I was bemoaning those who can't even be bothered to do ten seconds of research, not claiming that that's the maximum anyone ever needs to do.

This is an incredibly significant milestone in understanding an issue though. There are many many many people who entirely lack exposure to one half of the discourse on an issue; this is exacerbated by the fact that it's increasingly en vogue to consider it a moral failing to even consider the other side's arguments (even for the purposes of rebuttal).

Status quo it is then.
