When life gets difficult, our brains remember failures more easily than successes. It is called the negativity bias, and it can quietly erode confidence over time.
The evidence
Research shows people with greater optimism, self-esteem, and a sense of personal mastery maintain healthier biological responses to stress, even during challenging periods (Chiang et al., 2019). Why? Because they remember what they are capable of. Confidence isn’t pretending you’re fearless — it’s remembering you’ve overcome difficult things before.
The practice
Write down three strengths you’ve relied on this past year — perseverance, kindness, creativity, curiosity — and ask which one you can intentionally use today. Future confidence grows from remembered competence.
What mindspan measures
mindspan measures morning cortisol and DHEA-S together and reports their balance as a resilience index — the flagship metric of the Optimism Biology Report.
