Very interesting and helpful - and these techniques are not limited to the Society.
For example:
Ad hominem - Latin for 'to the man', attacking the arguer and not the argument (e.g., the Reverend Dr Smith is a known Biblical fundamentalist, so her objections to evolution need not be taken seriously).
I once posted some information about protein consumption at a bodybuilding website. The info quoted a nutritionist. Another poster Googled the nutritionist and posted a photo of her. Because she wasn't lean and muscular, the information was deemed useless by that poster, with no competing evidence presented to refute the information.
