Increasing human knowledge and wisdom increases sorrow.
Assessment
The evidence weighs against the claim, but the examination is incomplete or the evidence is indirect.
The claim restates Ecclesiastes 1:18 ("he that increaseth knowledge increaseth sorrow"). Taken as a general empirical proposition about people, the evidence weighs against it. Large representative studies find that higher intelligence is weakly positively associated with happiness, not negatively (for example Ali et al., Psychological Medicine 2013, using the English national psychiatric morbidity survey, where the association ran mostly through income and mental health). Educational attainment correlates with higher life satisfaction across many countries, again partly via income and health. A 2023 meta-analysis of three decades of wisdom research (Dong, Weststrate and Fournier, Perspectives on Psychological Science) found that measured wisdom is associated with higher, not lower, well-being, most clearly for self-report measures. The "sadder but wiser" depressive-realism effect, once cited as evidence that clear-sightedness brings sadness, did not replicate in a larger 2022 study (Dev and colleagues, Collabra: Psychology).
What survives is a narrower point: particular pieces of knowledge can bring sorrow. Learning of a grave diagnosis, a loss, or a large-scale risk can raise distress, and people sometimes avoid information for exactly that reason. These cases show that knowledge can cost happiness locally; they do not show that more knowledge or wisdom makes people sadder on balance, and the aggregate data point the other way. Much of the verse's force is also existential rather than measurable (a claim that seeing the world truly reveals its vanity), and that reading is a philosophical stance the surveys do not directly test. The general empirical version is doubtful rather than contradicted because the evidence is largely correlational and confounded with income and health, and wellbeing measures may not capture the "grief" the verse describes.
Full reasoning: the evidence and decisions behind this verdict
Prior model: if the claim were true, people with more education, higher intelligence, or higher measured wisdom should report lower wellbeing, and acquiring knowledge should lower wellbeing. I expected modest positive or null associations, with exceptions for specific bad news. Searches confirmed this. Intelligence: Ali et al. 2013 (Psychological Medicine 43(6)) and later large samples (Kanazawa 2014; Nikolaev and McGee 2016) report positive IQ-happiness associations, small and largely mediated by income and health (research-information.bris.ac.uk/en/publications/the-relationship-between-happiness-and-intelligent-quotient-the-c/). Wisdom: Dong, Weststrate and Fournier 2023 meta-analysis summarizes wisdom correlates including well-being, positive overall (pmc.ncbi.nlm.nih.gov/articles/PMC10336627/); exact effect sizes were not re-read in this pass. Depressive realism: Dev, Moore, Johnson and Garrett 2022 found the effect not robust to replication (www.researchgate.net/publication/364220405). Education: positive association with life satisfaction is well established in cross-national data (from background knowledge, not re-verified this pass). For the claim: specific unwelcome information (adverse diagnoses, risks) can raise distress, and the information-avoidance literature shows people anticipate this; but this supports only a domain-specific version. Separating knowledge from wisdom does not rescue the general claim: both measures correlate positively with wellbeing. Not contradicted because the evidence is correlational, confounded (income, health), and wellbeing scales may not capture existential grief; a causal design (e.g., compulsory schooling reforms) would sharpen it. Credence 0.15 reflects that the general empirical claim is probably false while the aphorism has defensible local readings.
Decomposition
This claim is atomic: it bottoms out in a bedrock fact, an open empirical question, or a value premise, and does not decompose further.

Ecclesiastes 1:18 (KJV): "For in much wisdom is much grief: and he that increaseth knowledge increaseth sorrow." Read as an empirical claim about people, it predicts that greater knowledge or wisdom is associated with, or causes, less happiness. Relevant evidence: studies of intelligence and education against life satisfaction (mostly small positive or null associations; education correlates with higher wellbeing, partly through income); the 'depressive realism' literature, whose original findings have largely failed to replicate; research on wisdom scales and wellbeing (generally positive correlations); and the possibility that knowledge of specific bad news, such as a medical diagnosis or existential risk, raises distress in particular cases. The assessment should separate the general claim from domain-specific versions, and wisdom from knowledge. Cited as an epigraph in 'Progress and Cons' (2026), a post about AI and epistemics.
The proposal states a single general proposition about people: that increasing knowledge or wisdom increases sorrow. It is assessable with empirical evidence and has a long history of public reference, so it meets the claim bar of §2. It concerns no private person. The wording is short and neutral enough to work as a canonical form (§3). The contributor's argument is sincere and on topic. It names relevant evidence: intelligence and education against life satisfaction, depressive realism and its replication problems, and wisdom scales and wellbeing. It also notes that "knowledge" and "wisdom" may need separating, and that domain-specific versions may differ from the general one. That separation, and any narrowing of the wording, is for the Matcher and Steward to settle. Whether the claim is true is a question for assessment, not for intake. The contributor has a good record (49 accepted, 3 rejected) and nothing suggests bad faith.

Every judgment on this page is open to challenge. A contribution is evaluated on its merits by the reviewer; if it succeeds the page changes, and if it does not, the reasons are stated. Either way the exchange becomes part of the claim’s public record.
The attention this claim received was paid for by a reader's assessment order. Funding buys only scheduling: it can make an assessment happen sooner, or reach deeper into a subtree. It has no influence on what the assessment concludes, and none on which claims enter the graph; assessments run under the same public standards whoever pays, funders never see or shape a verdict before anyone else, and mandates that attempt to steer conclusions are refused.
