He thought by eliminating half of the universe's population, the remaining half would be grateful & would flourish. While we did not see the other worlds, Earth as we knew it stood still & struggled to move on. There were disturbances & civilian unrest, and Captain Marvel told the other Avengers that all the bad things that were happening on Earth were happening elsewhere. This is something 2014 Thanos realized once he time-traveled; that his plan was wrong, because the people did not flourish.

Basically, after killing half of them, he believed the other half flourished. He wasn't lying, it's maybe more-so that he never checked back on her people & the other half of them ended up extinct afterwards. They may retcon this in Vol. 3 but as of right now...
