In desperate hole, Pinter grabs another shovel

In a recent interview with NBC News anti-YDB jihadi Nick Pinter claimed that “the pro-impact literature is, at this point, fringe science being promoted by a single journal.

This is nonsense — and easily disproven. The critics of the YDB hypothesis have published 10 times in PNAS (see #1 below), whereas the YDB proponents have published only 8 times (see #2 below). Where’s the bias by PNAS, one of the world’s most prestigious journals? There is none.

Also, let’s look at Pinter’s claim that the YDB impact hypothesis is only being argued in a single journal. Besides the 8 papers in PNAS, proponents have published 15 papers in 13 other journals (listed below and in #3). Pinter’s claim is obviously false.

Journals other than PNAS publishing evidence from YDB proponents:

Contemporary Issues in California Archaeology;
Earth and Planetary Science Letters (2);
Journal of Advanced Microscopic Research
Journal of Archaeological Science;
Journal of Cosmology;
Journal of Glaciology;
Journal of Geology;
Journal of Siberian Federal University;
Journal of the Geological Society;
Quaternary International;
Quaternary Science Reviews;
Sedimentary Geology (2);
