This document discusses cognitive biases and techniques to reduce their impact on decision making. It provides statistics on deaths from terrorism, firearms, and road accidents in the US in 2009. While $657 billion was spent on the "War on Terror", only $150 million and $850 million were spent on gun education and traffic safety programs respectively. The document then outlines general and specific cognitive debiasing techniques drawn from fields like decision theory, neuroscience, and behavioral economics. These aim to improve fact presentation, slow down reasoning, and increase accountability to make decisions less biased.
