The claim is:

    "most published scientific research is probably false"

and the evidence for that claim is:

    The number of false negative "might easily be 4 in 10, or in some fields 8 in 10" 

(quoted from the video)

This is rather weak.

And maybe more importantly: this assumes that researchers test random hypothesis uniformly drawn in the space of all possible hypothesis, which clearly isn't the case.

Anyway, this can't be really serious.
