Where the claims actually come from. Each topic walks through the original experiments, the methodology, what replicated and what didn't, and the open questions — then links out to the primary sources so you can verify and extend the work yourself.
Neuroscience
Predictive Coding & The Free-Energy Principle
The brain as a Bayesian prediction engine
Perception is not a feed from the senses upward — it is a hierarchy of predictions running downward, with only the prediction errors passed back up. This single architectural idea now organizes most of contemporary cognitive neuroscience.

Neuroplasticity & Sensory Substitution
The brain as a livewired device, not a fixed circuit
Cortex is not modality-specific by destiny. Whatever signal arrives at a region, the region learns to make use of it — which is why practice physically restructures the brain.

Default Mode Network & Contemplative Practice
The neural substrate of mind-wandering and what training does to it
There is a specific network in the brain that runs whenever you aren't directed at a task. It is the home of rumination, self-narrative, and time-travel. Sustained meditation measurably modifies it.

Global Workspace & The Bandwidth of Consciousness
Why the conscious channel is so much narrower than the brain
Sensory transduction operates at tens of millions of bits per second. Conscious access tops out around 40–60. The mechanism of that compression is one of the central problems in cognitive neuroscience.

Constructed Emotion & Affect Labeling
Feelings are not pre-packaged categories firing from dedicated circuits
The classical view — that emotions are universal, biologically-given categories with dedicated neural signatures — has been substantially undermined. Affect, on the constructionist view, is interoceptive prediction wrapped in learned concept.

Volition, Libet, and the Conscious Veto
What the readiness-potential experiments actually showed
Benjamin Libet's 1983 experiment is more cited than read. The strong 'no free will' reading is not what Libet himself concluded — and the subsequent four decades of replication have substantially complicated the picture.

Linguistic Relativity
How the language you speak modulates what you perceive
The strong Sapir–Whorf hypothesis — that language determines thought — was discarded long ago. The weak form — that language modulates perception and cognition through top-down priors — is now solidly established.

Philosophy
Interface Theory of Perception
The Fitness-Beats-Truth theorem and conscious agents
Donald Hoffman's claim is unusually strong: not that perception is imperfect, but that natural selection actively drives perception away from veridicality. The argument is a mathematical theorem, not a metaphysical intuition.

Time, Space, and the Evolving Lawbook
Why the substrate of physics may not be what classical physics described
A serious minority of working physicists now defend the view that spacetime is emergent, not fundamental — and that physical law is something the universe writes as it goes, not a fixed lawbook it obeys.

Practice
What Sitting Practice Actually Does
The current state of the meditation-science literature
The popular literature on meditation overclaims. The serious literature, read carefully, supports a narrower but still substantial set of effects — and the methodological standards are finally catching up.
