Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? Nine of the 11 reviewed interventions significantly increased conscientiousness at the trait, facet, or state level. → Melanie Turner 2025
q2 i? The 55% of studies reporting effect sizes showed small to moderate changes in conscientiousness. → Melanie Turner 2025

q2 · i? · quant-synthesis · r1
Systematic review synthesis (RQ3) of 11 studies published 2017–2024. The review reports "Nine out of the 11 interventions (82%) significantly increased participants’ conscientiousness"; one behavior activation intervention and one coaching intervention were not effective.
"Nine out of the 11 interventions (82%) significantly increased participants’ conscientiousness at either the trait, facet, or state level."
Discussion¶
Learner Variables¶
- Personality Traits — outcome: instruction changes it
Related Claims¶
- Digital coaching increased the organization and productiveness facets of conscientiousness but not responsibility, with no observer-reported facet changes — a narrower finding that bears on this claim
- Digital coaching significantly increased trait conscientiousness, with effects stable one year after the intervention ended — a narrower finding that bears on this claim
- Intervention gains in conscientiousness were generally maintained at follow-up, but mediation was never tested and only one intervention examined moderation — a narrower finding that bears on this claim
- Behavior activation interventions show a dose-response pattern — completing more conscientiousness challenges produced larger increases — but one behavior activation trial found no significant change — a narrower finding that bears on this claim
- One in-person coaching intervention produced a small significant reduction in conscientiousness while the control group showed no change — reports the opposite
