Why forgetting a thought in a doorway points to consciousness
Walk through a doorway and the thought you were holding vanishes. A Birmingham philosopher thinks that tiny failure points straight at where consciousness lives.
Hold a thought, walk through a doorway, lose it. Birmingham philosopher Henry Taylor says consciousness ignites when working memory hands its contents to attention, which broadcasts them brain-wide.
His proof cases include a study where 75% of phone-distracted walkers missed a unicycling clown. A neuropsychiatrist in the thread calls working memory mere CPU cache, wired beside consciousness, not its source.
Consciousness may be working memory with the volume turned up

University of Birmingham philosopher Henry Taylor argues in Scientific American that consciousness may switch on at one specific moment: when something held in working memory receives attention and is "boosted in volume and broadcast across the brain." He leans on the global neuronal workspace theory, in which a fragment of information becomes conscious once it is broadcast from a central hub. His everyday evidence is the doorway effect, walking into a room and losing the thought you carried in, plus a classic study in which 75% of people staring at their phones failed to notice a unicycling clown. No attention, no awareness.
Taylor concedes two problems with the equation. Working memory holds too little to account for how rich experience feels, and some of its contents seem to stay unconscious. His move is to make working memory a spectrum with a "grey area" between stored and not stored, so consciousness itself might come in degrees rather than flip on and off. The essay is adapted from one Taylor first published at The Conversation, as one reader pointed out.
The thread doubts the equation
A neuropsychiatrist reached for a computing analogy that severs the link Taylor wants to build:
"Working memory is exactly like CPU cache… Consciousness is a process that runs concurrently with the main process and follows it… WM and consciousness have little relation." — a physician specialized in neuropsychiatry
A second reader flagged the hidden assumption inside the model:
"there is the danger that the author assumes 'being available for cognitive manipulation or verbal report' to be synonymous with 'being conscious.'" — one reader on the theory's blind spot
And the oldest objection in the field arrived on cue, the Hard Problem:
"Even if we find a mechanistic way to explain what is needed for consciousness, it does not give any clue as to why it feels like something to be conscious." — a reader invoking the hard problem
Not everyone dismissed it. One saw the virtue Taylor is chasing:
"this is a specific enough theory that it might be amenable to experimental investigation." — a reader on the theory's testability
Taylor's bet is that consciousness is finally testable. The thread's split is narrower: whether he has explained consciousness, or only described its filing system.

You already have time to learn — it's between Netflix and your phone
Viktor Löfgren, who builds the indie search engine Marginalia, has a blunt answer for 'I don't have time': if you scroll your phone while Netflix half-plays across the room, you do. The catch is that the first sessions feel awful, and that is the point.
