Applied CI

How can we us CI to improve the human condition?

Promote Idea-Testing

Activate Antibodies to Mind-Parasites

Activate Antibodies to Mind-Parasites

A dropper putting red-pink liquid into a test tube.

Empower people to express their doubts with well-framed questions. Strengthen the cultural norm that requires us to yield to better reasons (rather than defy them to protect dysfunctional beliefs, desires, and attitudes).


Teach kids the scientific attitude. This is essential to proper idea-testing and healthy mental immune function. Help everyone grasp that idea-testing is a team sport—we need to take account of other people's doubts and challenges to gain deep immunity.

Activate mental antibodies. Help people understand that doubts and qualms are the mind's antibodies—we must listen to them if we hope to develop strong mental immunity.


Diagnose and treat mental immune disorders (habits of mind that interfere with rigorous idea-filtering). Cultivate the growth mindset (the fixed mindset is in fact a mental immune disorder).

Develop Mind-Vaccines

Challenge Willful Belief

A syringe and vials against a blue background.

Inoculate minds against misinformation, science denial, and propaganda. Develop "mind-vaccines"—instructional interventions that confer immunity to especially troublesome ideas and tendencies of thought.


Upgrade the brain's antivirus software—our standards of reasonable belief function like the "virus definitions" in antivirus software, but the standard our culture "preinstalls" in most of us exacerbates confirmation bias.

Challenge Willful Belief

Practice Critical Thinking in the Digital Age

Challenge Willful Belief

Three sculpted monkeys in the see-no-evil, hear-no-evil, say-no-evil poses.

Encourage people to believe responsibly.  Willful belief, which does not welcome contrary evidence or challenges of any kind, subverts mental immune health. Instead, promote the cultural norm that requires us to entertain doubts and, when presented with them, to yield to better reasons.

Resist Identity-Protective Cognition

Practice Critical Thinking in the Digital Age

Practice Critical Thinking in the Digital Age

Ostensibly, the internal image of a human head: a skull x-ray with an illuminated brain.

Teach people not to identify with their beliefs. Identity-protective cognition, in which people refuse any ideas that might threaten their sense of self, compromises mental immunity.

Practice Critical Thinking in the Digital Age

Practice Critical Thinking in the Digital Age

The internal workings of a computer.

Instill fair-mindedness online. When people weaponize critical thinking skills and reasons, they fuel the culture wars that compromise the mental immune health of everyone involved. Redesign education to confer deep immunity to toxic and divisive ideologies and teach best practices for online communication.

CIRCE Workshops

One of the most exciting and practical applications of cognitive immunology is through our workshops. Contact us for information about how to bring CIRCE to lead your group in trainings and seminars that teach the principles of cognitive immunology and help build mental immunity.
