Caused by: Purchase Fuzzies and Utilons Separately

As most readers will know by now, if you're donating to a charity, it doesn't make sense to spread your donations across several charities (assuming you're primarily trying to maximize the amount of good done). You'll want to pick the charity where your money does the most good, and then donate as much as possible to that one. Most readers will also be aware that this isn't intuitive to most people - many will instinctively try to spread their money across several different causes.

I'm spending part of my income on charity, too. Admittedly, this isn't much - 30 USD each month - but then neither is my income as a student. Previously I had been spreading that sum to three different charities, each of them getting an equal amount. On at least two different venues, people had (not always knowingly) tried to talk me out of it, and I did feel that their arguments were pretty strong. Still, I didn't change my ways, even though there was mental pressure building up, trying to push me in that direction. There were actually even some other charities I was considering also donating to, even though I knew I probably shouldn't.

Then I read Eliezer's Purchase Fuzzies and Utilons Separately. Here was a post saying, in essence, that it's okay to spend some of your money in what amounted to an irrational way. Yes, go ahead and spread your money, and go ahead and use some of it just to purchase warm fuzzies. You're just human, after all. Just try to make sure you still donate more to a utilon maximizer than to purchasing the fuzzies.

Here I was, with a post that allowed me to stop rationalizing reasons for why spreading money was good, and instead spread them because I was honestly selfish and just buying a good feeling. Now, I didn't need to worry about being irrational in having diversified donations. So since it was okay, I logged in to PayPal, cancelled the two monthly donations I had going to the other organizations, and tripled the amount of money that I was giving to the Institute Which Shall Not Be Named.

Not exactly the outcome one might have suspected.
