Final answer:
Conventional wisdom is a collection of beliefs or ideas widely accepted as true by the public or experts, forming part of the societal consensus.
Step-by-step explanation:
Conventional wisdom refers to a body of ideas or explanations that are generally accepted as true by the public or by experts in a field. These ideas have stood the test of time and have become entrenched in the collective psyche, often without being rigorously tested or challenged. Occasionally, conventional wisdom may turn out to be incorrect when subjected to scientific scrutiny, but it still plays a significant role in shaping public opinion and societal norms.
