OUR APPROACH
Behavioral Design
We use behavioral science to inform product decisions.
Behavior change is hard. A few customer interviews alone won’t crack it. Too often, teams start the product development process by asking people what they want or would use.
At Irrational Labs, we use a process call behavioral design. We study the environment of decision-making to create hypotheses about user behavior.
