The ICA and the MBTI® assessment in detail · The ICA and 16Personalities in detail
Grounded in three fields of research
The three faculty names come from Rudolf Steiner, and the wider idea that the mind knows, feels and strives runs through the history of psychology as the "trilogy of mind". The four-dimension structure is our own model.
Each of the four dimensions has a parallel in today's research. In analytical psychology, they line up with Jung's four functions: intuition, thinking, feeling and sensation. In behavioral science, the two Thinking dimensions mirror the distinction between intuitive and deliberate thinking. In neuroscience, they parallel four large-scale brain networks: default mode, executive control, mentalizing and sensorimotor.
Its accuracy is currently being studied in three stages, with findings published as each one completes.

Questions
What is the ICA?
The ICA is a free 40-item behavioral-preference assessment from ICAPsychometrics. Each item describes a situation and offers four responses; you choose what you would actually do. Your choices produce scores on four dimensions (Integrative Synthesis, Systematic Analysis, Social Attunement and Environmental Engagement), which group into three faculties: Thinking, Feeling and Willing. The result is one of 24 ranked profiles.
How long does it take?
About 15 minutes for most people: 40 items, each with four options.
Where are my answers stored?
In your browser. The online test scores your answers on your device and keeps your history in your browser's local storage. Nothing you answer is sent to us.
Is the ICA scientifically validated?
Its validity and accuracy are currently being studied in a staged research program. The model draws on established parallels in analytical psychology, behavioral science and neuroscience, and findings are published on the research page as each stage completes.
Is the ICA related to the "Integrated Cognitive Assessment" dementia test?
No. A different organization, Cognetivity Neurosciences, sells a medical screening test for cognitive impairment under the same name, Integrated Cognitive Assessment (ICA) (overview). ICAPsychometrics is not connected to it. The ICA does not measure memory, attention or any cognitive ability, and it cannot screen for dementia. If you are worried about memory or thinking, speak to a doctor.
