Scott Alexander examines how debates often revolve around vague concepts with positive or negative associations rather than specific claims, leading to logical fallacies and tribal thinking.

Scott explains that while people naturally use emotivism (the 'yay/boo' theory) for moral reasoning, this creates serious problems by lumping everything into 'good' or 'bad' categories, and argues that converting moral debates into specific questions about actions and applying utilitarianism provides a better framework for resolving complicated issues.

Scott examines the universal human bias toward supporting underdogs, presents evidence it significantly influences opinions, and asks why evolution would favor such an apparently irrational strategy.

Scott distinguishes between bias as a cognitive process versus bias as a faulty belief, then proposes using the Implicit Association Test to empirically test whether debiasing techniques work by either fighting bias directly or routing around it.
