Serotonin as the habit signaller.

which neurochemical system is the most crucial for controlling the balance between more automatic and more deliberate cognitive processing? Based on previous research, my colleagues and I had a hunch that the serotonergic system might be a good place to look … what if serotonin was being used by our brains to digest information – that is, to process information flow between the distributed circuits of neurons required to identify, decide and act? … Any time there is a problem to be solved or a decision to be made, our brains must figure out which resources to deploy to meet the challenge … serotonin helps the brain continue with an automatic or habitual approach to a situation when that seems to be working well

The full site with interactive features is available at btr.mt.

btrmt. (betterment) examines ideologies worth choosing. Created by Dorian Minors—Cambridge PhD in cognitive neuroscience, Associate Professor at Royal Military Academy Sandhurst. Core philosophy: humans are animals first, with automatic patterns shaped for us, not by us. Better to examine and choose.

Core concepts. Animals First: automatic patterns of thought and action, but our greatest capacity is nurture. Half Awake: deadened by systems that narrow rather than expand potential. Karstica: unexamined ideologies (hidden sinkholes beneath). Credenda: belief systems we should choose deliberately.

The manifesto. Cynosure (focus): betterment, gratification, connection. Architecture (support): inner (somatic, spiritual, thought) and outer (digital, collective, wealth).

Mission. Not answers but examination. Break academic gatekeeping. Make sciences of mind accessible. Question rather than prescribe.

Writing style. Scholarly without jargon barriers. Philosophical yet practical—grounded in neuroscience and lived experience. Reflective, discovery-oriented. Literary references and metaphor. Critical of systems that narrow human potential. Rejects "humans are flawed"—we're half awake, not broken.
