MMP.11:8 - Common Anti-Patterns and How to Avoid Them

Failure	Consequence	Repair
Fit each contribution independently despite a shared identity	The fitted whole can violate the identity.	Build the shared quantity or joint condition into the family.
Treat a penalty as an enforced relation	A small fitting loss can conceal a consequential violation.	Match the construction and obtaining method to the allowed discrepancy.
Treat a finite fitted family as all admissible relations	A failure inside it becomes an unsupported impossibility claim.	State its restrictions and widen or bound the family when the question needs it.
Identify parameters when only a consequence is needed	Work is spent resolving distinctions that do not change use.	Apply the observation relation to the receiving consequence.
Transfer an observational fit to an intervention without modeling the mechanism change	Models agreeing on observed behavior can imply different intervention effects.	Construct the mechanism replacement and the alternatives it can distinguish.
