The No-Spin Evidence Review

What We Do

We provide plain-language, no-spin summaries of recent studies on “what works” in social spending. We also highlight a common problem in study reporting: Study abstracts often portray programs as effective when the study’s results don’t support such claims.

We focus on abstracts because of their central role in research communication. Many readers rely on abstracts for a study's main take-aways - due to time constraints or paywalls on full-report access - so their exaggerated claims can lead to programs being mislabeled as “evidence based” and expanded despite weak or null findings.

Each No-Spin report assigns a rating – “accurately reported,” “somewhat accurately reported,” or “not accurately reported” – based on how well the abstract reflects the study’s primary findings and notes any important limitations that could affect study validity. We explain the basis for each rating and, where needed, suggest revisions to make the abstract more accurate.

We mainly report on randomized controlled trials (RCTs) because, when feasible and well-conducted, they're considered the strongest method of evaluating program effectiveness.

Recent reviews

  • Networks for School Improvement (NSI) to Increase the Proportion of Students On Track for High School Graduation

    Accurately reported

    Mathematica (July 2026) published RCT findings for Networks for School Improvement (NSI), a $300M Gates-funded initiative in which schools collaborate to use continuous improvement methods to test and refine strategies addressing a common challenge. This large, high-quality RCT found small positive impacts on academic and behavioral outcomes in schools focused on 9th grade improvement (e.g., moving the average student from the 50th to 53rd percentile), and no positive impacts in schools focused on 8th grade improvement, after 2-3 years of implementation.

  • A Brief “Social Belonging” Intervention to Promote College Persistence Among Incoming Students

    Not accurately reported

    Science (May 2023) published RCT results for a brief reading-and-writing activity to promote “social belonging” among incoming college students. Despite the abstract’s positive portrayal of the results, the study found null effects on one of its prespecified primary hypotheses – that the intervention would increase college persistence among students in groups with a low sense of belonging – and doesn’t report findings on its other two prespecified hypotheses.

  • One Million Degrees, A Comprehensive Support Program for Community College Students

    Accurately reported

    Annenberg Institute (March 2026) posted long-term RCT results for One Million Degrees, a program that provides financial, academic, personal, and professional supports to community college students in the Chicago metro area. This large, high-quality study found modest positive impacts on degree completion (3 percentage points) and on employment (4 percentage points) 7-8 years after study entry.
