Which of the following is considered a common negotiation tactic?

Flinch tactics are commonly recognized negotiation techniques that involve reacting visibly to an offer or statement to signal that it is unacceptable or to pressure the other party to improve their offer. This tactic works by creating an emotional response, which can lead the opposing party to reconsider their position and potentially offer more favorable terms. By demonstrating shock or displeasure, a negotiator hopes to disrupt the confidence of the other party and make them rethink their negotiation strategy.

Other options may involve various strategies or approaches within negotiation, but flinch tactics are particularly noted for their psychological impact and immediate effectiveness in shifting the dynamics of a negotiation.
