Comparing sociology to biology in particular ends up unflattering for the former. Biology is a lot more obviously successful than sociology. Sociology has so far failed to produce its equivalent to evidence-based medicine and whenever treatments it has tried to design for social illnesses have not delivered.
I don't think sociology is completely hopeless but given its track record so far I would sooner expect intelligence (and empathy, willpower, etc.) augmentation to cure whatever problems plague society than any attempt at "institutional change".
