Episode notes
Balance Intelligence Across Units To Avoid Weak Links
- Balanced distribution of intelligence across units improves training speed and reduces weak links in the chain.
- Some arms (engineers, signal corps) legitimately require higher proportions of A/B men.
Ratings Predict Training Success And Attrition
- Intelligence ratings correlated strongly with officers' judgments and training outcomes, especially eliminations in officer and NCO schools.
- Success rates fell sharply below C+ in formal training programs.
Follow A Three-Tiered Screening Workflow
- Screen every recruit: give Alpha to literates, Beta to illiterates, and individual exams for failures or special cases.
- Recall low scorers for Beta and reserve individual exams for about 5% of cases.
