Between 1978 and 1987, the independent labs NIH studied - all members of the Association of Independent Research Institutes (AIRI) - consistently showed a higher-than-average success rate of research grants. For some years, the advantage was slight, such as 1.3% in 1981. But in 1987, the gap widened dramatically: 44.7% of AIRI applicants won grants. In contrast, the overall average was 35.4%.
