do people who tolerate uncertainty have much less anxiety and depression?
“People who tolerate uncertainty have much less anxiety and depression.”

first, the part that holds
this one holds up. across many studies, people who score higher on intolerance of uncertainty report clearly more anxiety and more depression, and the link is moderate to strong by psychology standards (correlations around 0.5), so "much less anxiety and depression" for people who tolerate uncertainty fairly describes the pattern.
what we found when we went and looked
we read a 2011 meta-analysis in clinical psychology review that pooled cross-sectional studies. it found mean correlations between intolerance of uncertainty and symptoms of 0.57 for generalized anxiety and 0.53 for major depression. those are large associations for self-report psychology. a 2026 three-wave study of 5,291 adolescents found that higher baseline intolerance of uncertainty predicted rises in anxiety and depression symptoms over 6 and 12 months, even after adjusting for baseline symptoms. the odds of reaching elevated symptoms were about 1.5 to 1.6 times higher. the claim is right about the association. it says nothing about cause, and the prospective effects that remain after adjusting for baseline symptoms are small (standardized betas of 0.06 to 0.08), so anyone hearing "tolerate uncertainty and you'll be less anxious" is reading more into it than the data show.
assertion by assertion
| assertion | verdict | what the record says |
|---|---|---|
| people with higher tolerance of uncertainty have substantially lower anxiety than people with low tolerance | confirmed | a meta-analysis of cross-sectional studies found a mean correlation of 0.57 between intolerance of uncertainty and generalized anxiety symptoms (0.50 with obsessive-compulsive symptoms). limitation: these are mostly self-report questionnaires measured at the same time, which is cross-sectional and can inflate overlap. [1][5] |
| people with higher tolerance of uncertainty have substantially lower depression than people with low tolerance | confirmed | the same meta-analysis found a mean correlation of 0.53 between intolerance of uncertainty and major depression symptoms, nearly as strong as for generalized anxiety. limitation: cross-sectional, symptom levels rather than diagnosed cases. [1] |
| the gap shows up as lower rates (not just lower symptom scores) and holds over time | confirmed | in 5,291 adolescents followed for 12 months, higher baseline intolerance of uncertainty predicted higher odds of elevated generalized anxiety (odds ratio 1.56 at 6 months, 1.62 at 12) and elevated depression (1.55 and 1.53) after adjusting for baseline symptoms. limitation: one cohort, adolescents in a single country, and screening cutoffs rather than clinical diagnoses. a 2022 adult pandemic cohort in argentina found the same direction for uncertainty specific to the pandemic. [2][3] |
| popular framing: tolerating uncertainty causes less anxiety and depression, so building tolerance will lower them | overstated | the causal reading has partial support at best. once baseline symptoms are adjusted for, the prospective effects are small (standardized betas 0.06 to 0.08). in treatment studies for generalized anxiety (26 studies, 1,199 participants), therapy reduced intolerance of uncertainty along with anxiety and depression. therapy aimed directly at uncertainty beat standard cognitive behavioral therapy on intolerance and worry at the end of treatment, but the advantage faded by follow-up. this shows the two move together. it does not prove tolerance comes first. [2][4] |
both directions
for the speaker: the cross-sectional association is large and consistent: correlations of 0.57 with generalized anxiety and 0.53 with depression in the pooled data, and questionnaire-validation work describes medium-high correlations with worry, anxiety, depression and general distress. it is not just a snapshot. in a large adolescent cohort, intolerance of uncertainty predicted later increases in both anxiety and depression and higher odds of elevated symptoms 6 and 12 months later, after adjusting for where people started. an adult pandemic cohort found intolerance of pandemic-related uncertainty predicted anxiety and depression for up to eleven months. in generalized anxiety treatment trials, intolerance of uncertainty falls alongside anxiety and depression.
against: most of the evidence is cross-sectional self-report. intolerance-of-uncertainty scales and anxiety or depression scales share content and both track general negative emotionality, so part of the 0.5 correlation may reflect that shared content and the shared measurement method. after adjusting for baseline symptoms, the prospective effect is small (betas 0.06 to 0.08), which is far weaker than the cross-sectional correlation suggests. the 2011 meta-analysis found the link was not specific to anxiety: it was nearly as strong for depression and obsessive-compulsive symptoms. that fits a general vulnerability marker, and it may not be a lever that switches anxiety off. in the treatment data, the edge of therapy aimed directly at uncertainty over standard cognitive behavioral therapy had faded by follow-up. the claim also says "people who tolerate uncertainty", but the research measures a continuous trait. it does not compare two clean groups.
what this cannot say
the speaker named no source, so we can't say which study they had in mind. our pooled numbers come from a 2011 meta-analysis. we could not retrieve the abstract of a larger 2019 meta-analysis (181 studies), so we don't cite it. the prospective evidence we read is one adolescent cohort and one adult cohort from the pandemic period. none of this tells you what changing your own tolerance of uncertainty would do to your symptoms. "much less" has no defined size, so we judged it against correlations around 0.5, which explain roughly a quarter to a third of the variation in symptoms.
