In the intelligence package Jeff saw that his own IQ was 115. Not terrible he was at the top of average, for a moment he considered hitting the plus sign next to that number. Then imagined the addictive possibilities of increasing his intelligence at the push of a button. He could end up a freak of nature with a giant pulsing brain that couldn't walk under the weight of his own brain.
He searched around and started finding the IQs of his family and friends. He noticed alot of them were higher than his, and he changed that shaving off points until no one he knew had an IQ above 100. There were options how to apply this, the default would change reality so these people would always have been less intelligent. Alternatively he could change their intelligence and make them oblivious to the change and go about their lives with a little less brain power. The opposite was available he could make them aware how much dumber they were now and make them happy about it or think it was the work of aliens, or they wanted this and got a microlobotomy.
Going further Jeff saw he could change intelligence for area he could make his whole town dumber, the county, the state, the country, the planet, the solar system. There were some freaky option where he could dumb down the whole universe. The universal IQ was 6 digits long and the last digital kept ticking up.
With those possibilities Jeff decided he was going to be the smartest person around but he wasn't going to change his intelligence but downgrade everyone else's.
So he got to work.
