Carhart-Harris's Fractal Brain Finds No Patient Recovery
A team of researchers has published evidence that LSD speeds up brain activity and reorganizes it into fractal patterns — the kind of self-similar structures you see in ferns and coastlines.
Headlines are behaving as headlines do, but the implication is obvious and also entirely suspended. Yes, the topology changed, but why that matters remains locked away like the last piece of a jigsaw nobody assembled.
This is not new. In 2016, Robin Carhart-Harris's team at Imperial College showed that LSD increases connectivity between brain networks that normally operate in isolation. Their fMRI images were stunning — the papers cited fifteen thousand times. Yet PTSD patients in clinical trials did not report better outcomes because their brains lit up differently. Depression remission did not correlate with increased network integration.
The pattern was real. The therapeutic payoff was not. The current finding repeats the structure exactly. You measure something novel, the measurement is good science, and then the leap from topology to outcome fails. Fractal patterns are more interesting than simple connectivity. That is a problem disguised as a solution. More specific, which makes it sound more explanatory when it explains nothing at all. A fractal brain does not tell you whether a patient will recover or relapse, only that your scanner can detect something you couldn't detect before.
The pattern was real. The therapeutic payoff was not.
”The real question is whether this becomes a research dead-end or whether someone finally breaks the logjam and measures what matters. This means not the shape of the signal but the shape of the person six months later. Watch for studies that correlate fractal complexity with specific therapeutic outcomes in actual patients, not healthy volunteers. Until then you are looking at a very precise map of a territory you still cannot navigate. The joke is usually on the territory. But this time it might be on us.
