Neuroscience textbooks and psychoanalysis have long occupied opposite corners of the academic boxing ring. But a fresh analysis published in the journal Entropy suggests the two fields have been studying the same mental machinery all along, just from radically different angles.
Researchers from the University of Oslo argue that the brain's prediction system, one of modern neuroscience's most influential models, mirrors core ideas Sigmund Freud and his successors developed over 130 years ago. The finding raises an intriguing possibility: merging these perspectives might unlock a richer understanding of how human consciousness actually works.
At the heart of the comparison lies the prediction paradigm. Neuroscience has come to view the brain as a prediction machine that constantly generates expectations about what comes next, then adjusts those forecasts by measuring them against real sensory data flowing in. This continuous updating shapes how we perceive, act, and regulate emotion.
Psychoanalysis, meanwhile, has long described how people unconsciously filter experience through internal models shaped by past relationships. What neuroscience now calls "prediction," psychoanalysts have called projection, transference, and unconscious expectation.
"For over 130 years, psychoanalysis has developed psychological theories about how predictions take place at a subjective level, which cognitive neuropsychology is now studying at a physiological level," Erik Stänicke, lead researcher on the paper, explained.
The two disciplines are essentially describing identical mental processes from opposite vantage points. Neuroscience zooms in on the brain's biological mechanisms and computations. Psychoanalysis stays at the level of lived experience, examining how those same processes feel from inside a person's consciousness.
Take projection, a cornerstone of psychoanalytic thinking. When we assign intentions or feelings to other people, our brains actively shape perception to align with what we already expect. A woman might interpret a coworker's neutral comment as criticism because her brain has built a prediction model, based on childhood experiences, that the world is hostile. Neuroscience labels this "active inference," the brain's attempt to make reality conform to its expectations.
"Our previous interactions with other people gradually influence what we expect from future relationships and situations," Stänicke said. The brain doesn't just passively receive information; it actively tries to remake the world to fit its model.
Prediction Models and Psychiatric Symptoms
Both fields also recognize that minds crave stability. They seek to minimize uncertainty, a condition called homeostasis. The brain reduces chaos by leaning heavily on established expectations, even when those expectations distort reality.
This shared insight sheds new light on why some mental disorders persist so stubbornly. Paranoid ideation or an internalized critical voice, from this view, are rigid prediction models that feel stable to the person experiencing them, even though they're brittle and inflexible.
Consider someone who automatically expects rejection from others and interprets every social interaction through that filter. Reality may offer contradicting evidence, but the brain keeps reinforcing the prediction because certainty, even false certainty, reduces the anxiety of not knowing what comes next.
"Rigid and persistent symptoms may be stable but not very flexible prediction models," Stänicke noted. "These deeply rooted mental models can persist because they reduce uncertainty, even if they also distort how reality is perceived."
This convergence also explains why psychological healing takes time. Both frameworks reveal that expectations aren't merely thoughts we think consciously. They're embedded in procedural memory, the body's implicit learning system that governs how we instinctively respond to and interact with others. Changing these patterns requires new relational experiences, not just intellectual insight.
Effective therapy sometimes works precisely because the therapeutic relationship itself becomes a laboratory for building new predictions. Repeated safe experiences with a therapist gradually reshape the neural models that have been running in the background for years.
The researchers propose that neuroscience and psychoanalysis could strengthen each other. Neuroscience offers psychoanalysis a hard biological foundation for its concepts. Psychoanalysis offers neuroscience a window into how predictions actually feel and express themselves in real relationships and daily life.
"Bringing these two fields together can open up for a more holistic psychology, in which both neurological mechanisms and subjective experience are included," the team wrote. "In this way, we can understand subjectivity in a more scientific manner."
Author Jessica Williams: "It's striking that modern brain science keeps bumping into Freud's core intuitions, just with better equipment and less pseudoscience. That's usually a sign he was onto something real."
