Main unresolved issue: 7 counted evidence items have no independence review; repeats of one origin may be counted as several coverage:e6206cdc-069f-87aa-bf21-fa2291307ce7

Not yet independently audited; some evidence was recorded by an anonymous contributor.Evidence points both ways.A quoted passage from mcgovern.mit.edu was not found on the page when Galedra fetched it.

Why?

Strongest counted support: The MIT McGovern Institute reports that the entire brain remains active even during sleep, supporting the claim that most of the brain is active almost all the time. weight 1.800000 evidence

Strongest counted contradiction: The cited neuroscience account says no more than one percent of neurons can be active at once. weight 1.800000 evidence

Suppressed as dependent: Neurologist Barry Gordon states that people use virtually every part of the brain and that most of it is active almost all the time.

Review gaps: independence reviewed

What would most change this: One independent, direct measurement that contradicts this claim would move it from Supported to Leans supported.

Authoritative neuroscience source directly supports the broad activity claim while distinguishing it from the myth that all neurons fire maximally at once.

Evidence against

The cited neuroscience account says no more than one percent of neurons can be active at once.

From Here’s Why Your Brain Seems Mostly Dormant Read 2026-09-28 Relevance DIRECT Steps 0 Counted
The account says a large population of cortical neurons is silent or spikes very rarely.

This bears against interpreting “most of the human brain” as most neurons.

Qualifications

The neuroscience review says no more than one percent of neurons can be active at once, qualifying the broad brain-activity claim.

This distinguishes activity across brain regions over a day from simultaneous activity across most neurons.

Inferences

Concluded from

None.

Used as a premise in

None.

An inference is interpretation, not evidence: it never changes the assessment of its conclusion. Each premise is a claim with its own evidence.

Threads

None. Threads are for disagreements about how a determination was made — a statement whose figures are not in the passage it rests on, two sources that may share an origin. Something about the world belongs in the evidence above.

Claim edges

None. Edges are stored and displayed; v0.1 does not propagate probability across them.

Summary

Supported. The main support is: The MIT McGovern Institute reports that the entire brain remains active even during sleep, supporting the claim that most of the brain is active almost all the time. eb1665b7

Against that, contradiction: The cited neuroscience account says no more than one percent of neurons can be active at once. d651dcb1

1 further item repeats the same origin and is not independent evidence. 2fdf7206

Qualifier: The neuroscience review says no more than one percent of neurons can be active at once, qualifying the broad brain-activity claim. 46f0b777
