Some young-Earth proponents recently reported that rocks were dated by the potassium-argon method to be a several million years old when they are really only a few years old. But the potassium-argon method, with its long half-life, was never intended to date rocks only 25 years old. These people have only succeeded in correctly showing that one can fool a single radiometric dating method when one uses it improperly. The false radiometric ages of several million years are due to parentless argon, as described here, and first reported in the literature some fifty years ago. Note that it would be extremely unlikely for another dating method to agree on these bogus ages. Getting agreement between more than one dating method is a recommended practice.
I can see from Wein that there are posibly problems with the creationist results based on The argon dating method.
I don't know if they were trying to trick the labatory or they were all just working with the information at the time.
So I will quit my previous arguments regarding that and the Mt. St. Helens Lava.
I will have to read digest and better understand Weins article to reacess my thoughts on circular reasoning and
confirmation bias regarding the dating methods.
