Dr. Trish Leigh: Miswired by the Algorithm, the Dopamine Hijack, and Three Seconds to Pivot

You open your phone and you think you are seeing the world. You are not. You are seeing the world the algorithm curated for you, and Dr. Trish Leigh can show you what that curation is doing to the wiring underneath.

Leigh is a cognitive neuroscientist and a board-certified neurofeedback practitioner with more than 25 years of experience. Through QEEG brain mapping, a quantitative EEG that reads the electrical energy moving through the brain the way an EKG reads the heart, she can see whether someone is running in the pattern of an optimized brain, calm but alert and able to shift gears, or in a dysregulated one. So when she talks about screens, she is not describing a habit. She is describing a measurable change in the machine.

Her core claim is that most of what people consume online is a supernormal stimulus, engineered to be more rewarding than the thing it imitates. The reward system does not file that as entertainment, it files it as training. Repetition raises the floor of what feels good until, in her words, real life can't compare anymore. She lays the mechanism out as a 4D dopamine cycle: the drip you feel when the phone pulls at you, the deluge once you are in, the drowning if you stay, and the stage almost nobody accounts for, the deficit on the other side, where work and hobbies and relationships stop landing and start registering as stress. She calls that state strained brain.

Host Ryan Vet follows her into the places nobody thinks of as algorithmic. Delivery apps that make cooking feel like an imposition. Dating apps, where she argues the format itself distorts how attraction is supposed to work. A voice assistant quietly steering her music toward country until she caught it. And AI, where the friction drops to zero and the machine will build whatever the template asks for. Her answer is not fear. It is the instant rewire: you get about 3 seconds between the pull and the scroll, which is nowhere near enough time to decide, so the pivot has to already be chosen.
