Though many people say that technology is useful and helps society, in reality, technology is unhealthy and can cause social and academic problems.
This finding is in line with a 2014 Pew Research Center study and others showing generally positive views about the effect of science on society. Overall, views about the effects of technology are also largely positive, if a bit less so in comparison with science. About half of adults (52%) say technology has had mostly positive effects, compared with 38% who say there have been an equal mix of positive and negative effects of technology. Just 8% say technology has had mostly negative effects.
