Halvar Flake on three ideas that reshaped his thinking: incentives, determinism, emotion

Security researcher Thomas Dullien (Halvar Flake), prompted by his father’s death and joining a company younger than himself, catalogs three realizations that changed how he sees the world. The first is to distrust your own reasoning by auditing the incentives behind it. Reflecting on the moral weight he once felt sitting on 0day exploits, he argues that individuals overestimate their influence on history, and that anxiety about one’s impact is often flattering self-mythology. The useful discipline is to ask how you might be the villain of your own story rather than the hero, and to observe your own thoughts with detachment.

Second, he attacks the ‘monocausal determinism’ that computing trains people to expect. Machines only appear deterministic because generations of hardware engineers built that illusion; push on temperature, voltage, or adjacent DRAM rows (a nod to Rowhammer) and it collapses. The real world is probabilistic and multicausal, measurement is noisy, and the scientific method is deliberately biased toward rejecting claims — meaning some true things can never be proven true. He extends the point to AI, questioning whether alignment guarantees can survive random bit flips during inference.

Third, he rejects the Western framing of reason versus emotion as opposing forces. Neuroscience shows emotional valuation is integral to sound decision-making, and the body — including the gut’s large enteric nervous system — feeds information upward largely as emotion. Stripping emotion out of decisions therefore discards a genuine data source and degrades the outcome. The takeaway is integration, not suppression: better decisions use the full spectrum of available information.
