The low-ball technique is a persuasive strategy where an initial offer is made at a low price to entice agreement, but once the target commits, the offer is changed to a higher price or less favorable terms. This method plays on commitment and consistency, as people are more likely to stick with a decision they’ve already made, even if the terms change. It highlights how initial agreements can influence later choices and attitudes, often leading to cognitive dissonance when the individual realizes they’ve been misled.
