Teenagers who text more than 100 times a day tend to be more shallow, image-obsessed and driven by wealth—not to mention pretty bad at spelling. The study from the University of Winnipeg suggests that a lot can be learned about a person’ s personality simply from the number of texts they send. The most incessant texters often turn out to be a slightly more racist than others.
    The data was gathered over a period of three years from 2,300 psychology students at the University of Winnipeg. The theory the university study tried to test was that constant use of twitter and texting for communication results in a world where people have quick and shallow thoughts. The results indicate that students who text frequently place less importance on moral aesthetic and spiritual goals and greater importance on wealth and image. Strikingly the study states those who text more than 100 times a day were 30 per cent less likely to feel strongly that leading an ethical, principled life was important, in comparison to those who texted 50 times or less a day. In the most extreme cases, 30 per cent of the survey takers texted more than 200 times a day and 12 per cent texted at least 300 times a day.
