The good rule of thumb is you can trust The Wiki with all information that does not require very specialized knowledge (doing brain surgery based on Wikipedia is probably a bad idea) and is not connected to any current political or culture war controversy. If it touches the latter two, best you can do is use the links to the source material, while keeping in mind link selection would be heavily biased - and the bias in the text goes without saying. NPOV is a noble ideal, but the reality is very short of it on anything concerning politics or culture wars.
