Is IQ an actual good measurement of intelligence?

IQ isn't particularly good at measuring individual success. As there are a lot of over educated fools and a lot of janitors with high IQs. But what it is really good at is predicting the behavior of groups. Like you can very easily tell will a specific group of people say, go to prison more based on IQ.
 
I think it means you will do better in the education system, which (on paper) might translate into a good job but as far as general success in life there's too many factors to count. There are plenty of succesful people who are legit retarded, a lot of people go by simply being clever or charismatic, i think plain luck has a big role in life. IQ is not a guarantee but would be a big boost but only if it is combined with other factors.

Sometimes all the planets align and you have someone who is born into a privileged family, in the right place at the right time, is high iq and naturally skilled and also a disciplined hard worker and those factors combined create the kind of success that will have a big impact but it is not very common, most people would be lucky to have one of those things in their favor and people have to play with the card they are dealt. For the top 1% of geniuses in a field there's need to be some natural talent though, its just what it is, hard work is great but two people can work just as hard and one be a genius and the other mediocre, thats life.
 
If someone takes an IQ test 3 different times and scores a 70 3 different times, that person is probably retarded

But we should come up with a new IQ method. Maybe some kind of practical hands on method.

Get 100 people, give them all a puzzle and see how fast they can put it together,
Then base iq off of the average completion time. You can account for pros who finish really fast because they do puzzles a lot and retards who take way too long.
