The carbon footprint from running shoes

Whenever I fly, I always pay the extra $ for what the airline I usually use call ‘carbon offsets’. As I travel a lot (probably too much), it gives me the warm fuzzies known I have done something to reduce the carbon footprint of my travel. During the last few weeks I was a parent […]

The ‘appeal to antiquity’ fallacy

I have already written on a number of other fallacies that often get used. The ‘appeal to antiquity‘ is another commonly used logical fallacy that is often used when the assumption is that something is better because it is older, is traditional, or has “always has been done.” An often cited example is: “Homeopathy has […]
