I agree, if we limit the statement to the quoted piece.
But I think the full line is true as it stands.
> The danger is when/if people selectively choose studies, that just so happens to repeat what their ideology would dictate.
I.e. that the danger doesn't come from being selective based on methodological soundness as you say, but based on e.g. ideology.
There's also you can't get an ought from an is, the is–ought problem. The facts don't guide your action at all, not even in an imagined neutral unbiased dispassionate way. They can only change minds as part of an argument, and the argument is going to have ideology behind it.
