Reading the research behind popular ideas about mindset.
Cairn Post reviews published work in behavioural science — what a study measured, how large the effect was, whether other laboratories reproduced it, and where the literature disagrees with itself. Each entry names the researchers and states the objections alongside the findings.
Evidential footing
A cairn is a stack of stones left on a trail to mark ground that has already been walked. Every entry in the library carries one, and the number of stones records how well the underlying research has held up when other teams attempted to reproduce it. The marker is editorial judgement about the published record, not a rating of any reader's circumstances.
- Supported. Independent replications and meta-analyses point the same direction, with the usual caveats about effect size.
- Mixed. The original result survives in some populations or specifications and shrinks or disappears in others.
- Contested. Large pre-registered attempts to reproduce the effect have not recovered it, and the dispute is live.

Three entriesGrowth mindset after the replication wave
Carol Dweck's laboratory findings, the meta-analyses that reduced the estimated effect, and the large national study that recovered a small one in a narrow band of students.
Ego depletion and the willpower battery
Roy Baumeister's radish experiment became one of the most cited results in social psychology. A twenty-three-laboratory registered replication reported an effect near zero.
Implementation intentions and the if–then form
Peter Gollwitzer's specification effect is among the better-replicated results in goal research, though the meta-analytic estimate has been revised downward as publication bias was modelled.
Four rules the desk works to
- Nothing is assumed about the reader. Entries are written in the third person and describe published research only. Cairn Post holds no information about any individual reader and makes no statement, direct or implied, about anyone's circumstances, abilities, health or personal history.
- Researchers are named. Every claim traced to a study identifies the authors and the publication, so the original can be located and read directly.
- Disagreement is printed alongside the finding. Where a result has failed to reproduce, or where a meta-analysis has revised it downward, that appears in the same entry rather than in a correction later.
- No outcome is promised. Cairn Post publishes description of research. It does not present material as a method, system, protocol or sequence of steps that produces a result.
What Cairn Post is not
- Not therapy, counselling, coaching or any form of professional advice.
- Not diagnosis, treatment or medical guidance of any kind.
- Not personalised guidance. Nothing published here is written for, or about, any particular individual.
- Not a promise of any outcome, benefit or result.
- Not a crisis or emergency service. Anyone in immediate danger should contact local emergency services.
- Not intended for anyone under 18 years of age.
About this publication
What does Cairn Post publish?
Written reviews of peer-reviewed research in behavioural and cognitive science, concentrating on mindset, habit formation, motivation and self-regulation. Entries summarise what was measured, how, in whom, and what happened when other teams repeated the work.
Is the library free to read?
The library on this site is open and requires no account, subscription or payment. Where a separate paid publication is offered, its price, contents and terms are stated in full on its own order page before any purchase.
What is the refund policy?
Paid materials carry a 30-day refund window from the date of purchase, requested by email. The full terms are on the refund page.
Does Cairn Post offer consultations?
No. There are no sessions, assessments, coaching calls, plans or one-to-one services of any kind, paid or unpaid. Correspondence is limited to editorial and administrative matters.
Why are there no testimonials or success stories?
Cairn Post does not publish testimonials, reviews, case studies, before-and-after accounts or reader outcomes anywhere on this site or in its advertising. Individual accounts cannot establish that a published effect is real, and presenting them as evidence would misrepresent the research this desk reviews.
What happens to data collected here?
The site collects the minimum needed to operate, plus any message sent voluntarily to the support address. Legal bases, retention periods and the rights available under the LGPD and the GDPR are set out on the privacy page.
