Joe Carter gives us some good context for today:
The fact that many people agree on something does not imply that what they agree on is true, whether the issue is climatology or farm subsidies. An appeal to consensus is merely a form of the argumentum ad populum fallacy (appeal to the majority). The status of the fallacy doesn’t change just because the members of the majority all have Ph.Ds. If you want to establish a consensus for your argument, you have to do more than appeal to a consensus.
What’s this context for? Today’s WSJ includes the text of a letter sent from Sens. Snowe and Rockefeller to ExxonMobil CEO Rex Tillerson.
