a strategy for expressing a concessive conditional construction where the protasis, which specifies the set of conditions for the concessive conditional, invokes the two polar alternatives possible in the scalar model; the apodosis expresses the unexpected opposite of the expected causal relation between either alternative and the outcome, and so implies the same outcome no matter what. Example: Whether he is right or not, we must support him uses the alternative concessive conditional strategy -- either he is right or he is wrong, and under either of those conditions that make up the scalar model, we must support him.
