Lots of ways. Simple ones:
1. Time. Each test question have 1 minute to answer. The test author took 4 hours to write the question (before having an organization put it through a battery of tests and analyses to validate it).
2. Group effort. Test authors work in big teams; many brains makes for easier insight.
3. Children's IQ is normalized to their age scale; a 7-year-old with IQ 140 isn't cognitively equivalent to a 35-year-ld with such IQ.
