Broaden-and-Build, Made Practical

Using positive emotions not just as rewards but as resources that build lasting psychological strength

What is Barbara Fredrickson’s broaden-and-build theory and how do you use it?

Barbara Fredrickson’s broaden-and-build theory proposes that positive emotions — joy, curiosity, love, gratitude, awe — temporarily broaden thought-action repertoires (making thinking more flexible and creative) and, over time, build durable psychological resources including resilience, social connection, and cognitive flexibility. The theory is supported by experimental evidence for the broadening effect; the longer-term building effects are primarily observational.

Positive emotions have historically gotten less scientific attention than negative ones because they seem to lack the survival urgency. Barbara Fredrickson’s broaden-and-build theory changed that framing. Positive emotions, she argued, serve an evolutionary purpose distinct from negative ones: not immediate threat response, but the gradual accumulation of skills, relationships, and resilience that enable long-term thriving. Her research at the University of Michigan and then UNC showed that the ratio of positive to negative emotions predicts resilience and recovery from adversity — not because negative emotions are bad, but because positive ones build the reserve that makes negative ones survivable. The practices below are grounded in this framework with an honest assessment of what the evidence actually shows.
