Short answer: No, IQ has not been discredited as a measure of intelligence, but maybe there is more to the scope of intelligence than what it measures. Long answer: The g form of IQ is still valid. Based on context in which a test is taken, there may be some type 2 error (people scoring lower than actual IQ), but relatively little type 1 error (people scoring higher than actual IQ). That said, many researchers have asked if g is the be all and end all of intelligence. Research suggests that g tends to focus on the analytic and verbal parts of our brains. Howard Gardner found through research on aphasia patients that there are areas of our brain that function largely outside of what g measures. Others have found that while IQ floors may exist for certain professions (e.g., 120 for lawyers), IQ is not always the strongest predictor for success -- things like EQ often have stronger predictive value. Note that some of the derivative works of multiple intelligences, EQ, etc. are twisted interpretations of the original ideas, so be careful when reading the non-seminal works. Some people have co-opted the term "intelligence" in their derivative works in an effort to support a political agenda that may not necessarily be true to the original idea or even constructive.
