My greatest hits - things I write which are longer, more developed, and more well-researched than the blog posts. Many of them are cross-posted at LessWrong.
The Continuum - Visualizing Arguments - An essay explaining a method of 'graphing' an argument, something I came up with back when I was still interested in data visualization.
Knowing What You Know - Discussing the availability heuristic, and the context-dependence of human thought.
Don't Think Too Hard - What happens to your brain when you're dreaming, and what it suggests about our thought processes.
Why You're Stuck in a Narrative - A neurological account of the narrative fallacy.
