Uniform or fair
Clinical & experimental assignment
Random assignment helps separate treatment effects from pre-existing differences.
Evaluation card
What “plenty” means here.
- Required property
- Allocation concealment, the intended balance or stratification, and reproducible audit records.
- If it fails
- Predictable assignments influence enrollment or create systematically different groups.
- Relevant attacker
- Often not a hacker: a researcher may consciously or unconsciously steer participants.
- The Plenty Line
- Use a reviewed randomization service and preserve the protocol, seed custody, strata, and allocation log.
- Why more is not automatically better
- More random bits do not replace adequate sample size, blinding, or sound experimental design.

The Plentropy rule
Protect the requirement, then stop.
Use a reviewed randomization service and preserve the protocol, seed custody, strata, and allocation log.
Once that claim has comfortable evidence and margin, improve the next limiting factor instead of worshipping a larger entropy number.
