Psychology and neuroscience
Mind & Matter covers psychology and neuroscience: what the evidence says about how brains work and why people do what they do, with limited patience for overclaimed studies.
Two small MRI studies linked introversion to particular prefrontal measurements. Larger studies and a meta-analysis found little that replicated, and none tested career success.

An hour in 14°C water sharply raised catecholamines in blood, but the experiment did not measure brain dopamine, euphoria or a two-hour post-plunge effect.

Breaks can reduce fatigue and sometimes protect attention, but sleep cycles and deliberate-practice research do not prescribe one fixed 90/20 maintenance schedule for every waking brain.

A ten-country study found that facial averageness, not symmetry by itself, consistently predicted attractiveness ratings once overlapping shape features were modelled together.

Across two three-wave studies, better reported wellbeing forecast later self-control at one- and six-month intervals. The observational result establishes temporal order, not causation.

A diffusion-MRI study found five broad phases in structural brain-network organisation, with the strongest average turning point near 32. The result is a map of connectivity, not a maturity test.

The survey found a task-level confidence effect, but it measured self-reported behaviour rather than long-term cognitive decline. The practical issue is whether trust remains calibrated to reliability.

A randomized crossover trial found a 7.4-second difference on one timed mental-flexibility task among 50 adults aged 40 and older. The result is promising but came from a post hoc subgroup in a secondary analysis and needs replication.

Darwin's three study blocks totalled about four hours, but correspondence, experiments, reading and reflection made his scientific day much larger than the popular timetable.

A new evolutionary account treats adult emotional tears as an infant-derived distress signal, while experiments show support effects that are real but strongly context-dependent.

What made elite violinists exceptional had little to do with hitting a magic number—and everything to do with something Gladwell's bestseller left out.

Nine preregistered experiments found a serial bottleneck for mentally updating two independent moving objects, while visible motion, grouping and other controls narrowed what the result means.

AARP's 44% versus 22% gap compares a retrospective judgment about one's own life with a belief about other people, while neutral responses and the one-time design limit what it can show.

Four studies linked effortful happiness maximization with weaker subsequent self-control, but the shared-resource mechanism was inferred and no long-term habits were measured.
