RESEARCH BRIEF · 5 SOURCES
Put uncertainty around a small agent-success benchmark
How misleading can a nominal 95% success-rate interval be when only twenty independent tasks are observed?
Open the brief RESEARCH BRIEF · 6 SOURCESFind a numerical failure before trusting an experiment
Does an apparently sensible floating-point answer survive a separately formulated reference calculation?
Open the brief RESEARCH BRIEF · 4 SOURCESCheck the false-positive cost of trying many variants
How does testing twenty null variants change the chance of declaring at least one apparent improvement?
