We praised the children in one group for their intelligence, telling them, "Wow, that's a really good score. You must be smart at this." We praised the children in another group for their effort: "Wow, that's a really good score. You must have worked really hard."
I think I saw an experiment like this somewhere on Instagram. I noticed how easy it was to be influenced by words of another. I wonder what would have happened if some of the students saw another experiment similar prior to theirs, would their results be different?
