Answer: The decision-making bias described in this scenario is known as framing bias.
Explanation:
Framing bias occurs when people's decisions are influenced by the way in which information is presented or framed to them. In this case, the senator was able to change public opinion in favor of his legislation by reframing it in a way that made it more appealing to the public.
The name "omnibus tax increase act" likely presented the legislation in a negative light, as it emphasizes the fact that taxes would be increased. However, by renaming it "an act to protect the American way of life," the senator was able to reframe the legislation as something that would benefit the public and protect their way of life. This change in framing likely made the legislation more appealing to the public and helped the senator to gain support for it.
Framing bias is a common decision-making bias that can influence people's perceptions and decisions in a variety of contexts. It is important for individuals to be aware of this bias and to try to consider information objectively, rather than being swayed by the way it is presented.
