Does a claim have merit? (Does the claim accord
with what we already know/have experienced?)
Is it ambiguous? (Does the claim need further
interpretation? Is it worded too strongly?)
Does it require further support? (Would a claim/piece of
evidence be more plausible if it had more
reasons/evidence to support it?)
