Parental Investment Theory: Why Men and Women Want Different Things

Dating, Solved: Why Finding the Right Person Feels So Hard · Feb 4, 2026 Science

Whichever sex invests more in reproduction becomes the choosy sex. For humans, that gap is enormous — 9 months of pregnancy versus rolling over and making a sandwich. This single asymmetry, articulated by biologist Robert Trivers in 1972, explains why women are choosier, why men compete harder, and why men and women have been frustrated with each other since the beginning of time.

Darwin and Sexual Selection: Why Is Dating So Hard?

At 12:04 · chapter starts 8:40

Mark begins the science section with a genuinely interesting question: why is mating so complicated for humans when every other species just gets on with it? The answer starts with Darwin's 1871 book 'The Descent of Man' and the conundrum of the peacock — a creature whose gigantic, useless-for-flight tail only makes sense if you posit a second evolutionary force beyond survival. That force is sexual selection, which runs simultaneously with natural selection and determines which genes actually make it into the next generation. Mark explains Darwin's two sub-processes: intra-sexual selection (competition within a sex, like rams butting horns) and intersexual selection (one sex choosing from the other). Every form of human status display — from fancy cars to elaborate grooming — is a modern expression of these ancient mechanisms.

The Door-Keeping Experiment: Our Irrational Addiction to Optionality

In Dan Ariely's door experiment, participants sacrificed the highest-reward door — repeatedly — just to avoid seeing other doors disappear. Even when researchers trained them to use the best door, they kept wasting clicks to maintain options. This is the bias that runs our lives: we'll take a worse outcome to preserve the feeling of optionality.

Dan Gilbert's Psychological Immune System: Why Your Brain Justifies Every Decision

Finding Your Life Path, Solved · Sep 2, 2026 Science

Dan Gilbert discovered that the brain has a 'psychological immune system' — it misremembers, reframes, and rationalizes to keep you satisfied with whatever you chose. The fear before commitment is all about potential regret. But after committing, your brain quietly starts justifying the choice — and the more irreversible the decision, the stronger the effect.

The Placebo Effect Is Not Fake — It Just Belongs to the Story, Not the Drug

#403 ‒ Peptides: separating scientific promise from marketi… · Aug 10, 2026 Science

Peptides come loaded with a powerful narrative: regenerative, subcutaneous, targeted, cutting-edge. That narrative can genuinely move outcomes, especially for pain, energy, and recovery. The RCT's job is to quantify how much additional benefit comes from the molecule itself — above and beyond the compelling story surrounding it.
