Perhaps you’ve heard of carbon offsets: the idea that if you’re going to do something that will release greenhouse gases into the atmosphere, you also buy or support something that will sequester an equivalent amount of carbon. It’s a rational way to compensate for necessary activities and keep your damage to the environment neutral.
Well, how about stupid offsets? Let’s say you’re going to do something that will increase the net amount of stupidity in the universe, like, say, paying to watch some inane creationist propaganda film because you’re curious about just how bad it can be. You can, without feeling guilty, if for every dollar you spend on the dumb movie you also invest an equivalent amount in something that increases intelligence, like donating to the NCSE. It’s an excellent idea: if you absolutely must pitch a few dollars into the pockets of lying frauds, make sure you counterbalance the problem and buy Truth Tickets, too.
And even if you don’t want to see the stupid movie, you can still buy Truth Tickets to compensate for all the idiots who will.
