Just playing the cards here, but if my IQ is 155 and yours is 120. Why should I listen to you? A few possible reasons, some overlapping to various extents, not applicable to all situations. - The person with 120 IQ is a subject matter expert in this particular matter and you are not. - IQ is an approximation. It is probably the best one we have, but it is a very blunt and generalized metric. It is not evenly distributed across all areas of reasoning and functioning. A person with a 155 IQ or even a 200 IQ is going to be great at many things and awful at others. A person with 120 or even 80 IQ may be better in specific areas. - Both you and the 120 IQ person might be overqualified for the matter at hand, so your "extra" intelligence is irrelevant. - The person with 120 IQ is representing something larger than themselves, the accumulated wisdom of which dwarfs yours (imagine, I don't know, a 120 IQ forest ranger telling you how you should/shouldn't interact with particular flora and fauna) - It may be a situation where it is impractical to have individualized rules for highly intelligent or highly capable individuals.
