As the study defines critical thinking: yes it does.
The study claims, essentially, relying on a machine that solves a Problem for you, lessens your critical thinking skills.
Their Definition of "critical thinking" is just, at least to me, way Off.
Just because i can conprehend Stuff i read for example, does not show critical thinking. It just shows i can repeat shit i read adequately.
It's just bad science.
Americans or people?
Edit
Of course americans
