What predictions can the social sciences make with high certainty?

Apologies if the question is overly broad. I know many people criticize the social sciences for being too "soft" or "fuzzy". Where it that entirely not the case?

One prediction we can safely make in the child/youth/family welfare space is:

The earlier you provide a welfare intervention in the life of a person, and the life of the issues they are experiencing, the cheaper and more effective that intervention will be. 

For example - best way to reduce youth crime is to find the early warning signs (like skipping school, early drug use) and support the young person before they commit serious crimes. It's more effective and about 50 times cheaper.
