1. In this whole series of posts you are silently presupposing that utilitarianism is the only rational system of ethics. Which is strange, because if people have different utility functions Arrow's impossibility theorem makes it impossible to arrive at a "rational" (in this blogs bayesian-consistent abuse of the term) aggregate utility function. So irrationality is not only rational but the only rational option. Funny what people will sell as overcoming bias.

2. In this particular case the introductory example fails, because 1 killing != - 1 saving. Removing a drowning man from the pool is obviously better then merely abstaining from drowning an other man in the pool.

3. The feeling of superiority over all those biased proles is a bias. In fact it is very obviously among your main biases and consequently one you should spend a disproportional amount of resources on overcoming.
