PHY.8:8 - Common Anti-Patterns and How to Avoid Them

Anti-pattern	What fails	Repair
Equal weights from a count of alternatives	Two energy values are treated as equally likely despite a biased preparation.	Construct the weights from the reservoir, preparation or other applicable grounds.
Independence from separate constituents	A common preparation or fixed total disappears from the joint account.	Form the collective law before discarding dependence.
Mean as a prediction of every run	An excursion-sensitive device is assessed only at the mean signal.	Compute the fluctuation or threshold consequence needed for that device.
Equilibrium without an available settling interval	A stationary distribution replaces the prepared transient.	Compare the relevant relaxation with the observation time.
Sampler steps as elapsed time	Artificial moves become a claimed physical transition law.	Separate distribution sampling from a physically calibrated evolution.
One successful statistic validates the whole reduction	Mean-square agreement is used to justify a boundary-arrival probability.	Compare the observable that the changed question actually consumes.
