Answer: framing effects
Explanation: The framing effect is a cognitive bias(deviation from rationality in judgement) whereby decisions are made on options based on whether the options are presented with positive or negative implications that is, presented as a loss or as a gain.
Most people tend to lean towards an option when it is presented with positive outcomes while against when negatibe outcomes are implied. Gain and loss are defined as descriptions of outcomes and JB Kynfield is attempting to persuade his boss with the promise of "unheard amount of money".
