Is a comma needed before the word "which" and "such as" in the following examples?
Ethical clearance was essential which was obtained very early in the research process.
There are several reasons for this misconception such as a false belief in one's ability.

I agree that the second sentence needs a comma before ‘such’. The first sentence, however, requires careful consideration. To begin with, it might make for easier reading to recast it as:
It is the convention not to place the relative clause between commas when the information contained in the relative clause is integral to the larger message. So, the sentence as shown above distinguishes the clearance which was obtained very early in the research process from the implied clearance which was obtained at some other time in the research process. However, if we punctute the sentence as:
then the information contained in the relative clause is supplementary to the larger message. By putting the relative clause between commas, we are saying that ethical clearance was essential, and we happened to obtain it very early in the research process. Of the two, that seems to be the more likely intended meaning.
