We argue that Madole & Harden's distinction between shallow versus deep genetic causes can bring some clarity to causal claims arising from genome-wide association studies (GWASs). However, the authors argue that GWAS only finds shallow genetic causes, making GWAS commensurate with the environmental studies they hope to supplant. We also assess whether their distinction applies best to explanations or causes.

US law continues its historical trend of growing more permissive towards actors who engage in violent action in purported self-defense. We draw on some informal game theory to show why this is strategically irrational and suggest rolling back self-defense doctrines like stand your ground to earlier historical precedents like duty to retreat.
