An independent reference on applied psychology
Psychological science, put to work.
How research on minds and behaviour actually gets used — in workplaces and teams, in design and technology, in classrooms, in sport, and in everyday decisions. Concept, evidence, application. Nothing else.

How every entry works
Concept. Evidence. Application.
The concept
What it is, in one plain paragraph. No jargon a manager or a coach couldn't use by Monday.
The evidence
The studies that hold up — and how strong they are. Every entry carries a rating, and we say when a finding didn't replicate.
The application
Where it's actually used, and how — in hiring rounds, interfaces, training plans and race-day routines.

icap2014.com began as ICAP 2014, the International Congress of Applied Psychology in Paris. The congress ended; the domain stayed, and became this independent reference.
