PolitiFact's Bill Adair skirts the issue of selection bias on C-SPAN

For a second there I thought PolitiFact editor Bill Adair was going to do it.  He was going to admit that PolitiFact "report cards" are pretty much worthless because of selection bias.

Not quite.  He dropped a few hints but avoided the confession.  Check it out:

The almost-confession is drowned out by Adair's language hinting that the main problem with the individual truth ratings comes from small sample size. Good grief. Update 1/19/2018 C-SPAN allows users to make custom clips of its videos. Thanks to that feature, we have clipped the segment down to its relevant section.
