On the other hand, IIRC Peter Moore, the protagonist in Lazlo Zalezac's 'Reset Manifesto', denies being a genius; he merely utilises the skills of those who are geniuses. However, IMO Peter Moore is a good fit to my idea of what makes a realistic fictional genius, and any authors wanting to include a genius character in their stories would do well to read this story.
Genius is often used synonymously for a particular "idiot savant" type of talent, e.g. mathematics or music. Peter Moore's intelligence is more general in nature and really can't be adequately quantified. IQ tests are notoriously inadequate for such cases. Not saying they don't have their uses but I feel they tend to return many false negatives; in other words, a lot of time they don't pick up true talent.
What was Moore's real talent? IMHO, the ability to craft tools from disparate parts in order to achieve an objective. Much like early man crafted tools (examples are spears and other weapons) once an objective was identified. For some of my snobbish engineering friends, they'd say he was just a talented engineer, i.e. a good problem solver. Maybe. But given the breadth of his achievement, that characterization would fall a bit short.
I may have just gone the long way around to say I agree with you -- he was a genius, fictional or otherwise. And one of my favorite Zalezac characters.
