more than half of social science "experiments" have findings that can't be recreated.

This  reminds me of signal detection experiment used in a factory to measure "human inspection" performance.

The results showed that the false alarm rate was just shy of 50% and the miss rate was also 50% in the plant. 

that means..you could get rid of the entire inspection process and save money.

The same with social science it seems.  You could make assertions randomly and be just as right.
