I think what you're referring to is conscientiousness, the ability to stick to a task to completion regardless of how exciting it is. So you can get people with higher intelligence and low conscientiousness being overtaken by less smart people high in conscientiousness who actually finish the task. My understanding is that with a higher IQ you finish a task quicker . So smarter people tend to get to success quicker but doesn't mean that lower IQ folk are denied successes if both groups have similar levels of conscientiousness. IQ is not the strongest predictor of success.
