Simplified characters were introduced in Mainland China with the intention that this would improve literacy by making reading and writing easier. This seems intuitive: a character like 學 looks a lot more intimidating than 学 if you are considering the number of strokes. But I think it may not be much more difficult for native speakers who don't need to learn characters stroke by stroke. Also, literacy doesn't seem to be a problem in regions where complex characters are still used: This site https://worldpopulationreview.com/country-rankings/literacy-rate-by-country shows a 99% literacy rate in Taiwan vs. 97% in Mainland China.
Of course it's possible that it takes children slightly longer to reach full literacy in Taiwan, which would mean Mainland Chinese children can use that time to learn other things.
Have there been any published studies comparing learning effort between simplified and complex characters, and if so do these indicate that there is an advantage in simplifying?
