The one thing about the study that honestly bothers me is the messages they kept using a as a reference for texting. Of course you're going to seen like an emotionless robot putting period after a one or two word response. On the other had if you write out and actual sentence and add a period its a whole different story. I personally think that this study was flawed by the researchers going into it with a biased outlook from the get go. It would have also been nice if they actually took their subject sample from more than one place and age group. I like how they pointed out that people didn't react negatively to it when it was a note with a period, of course because once again it isn't a damn two words response.
Also why didn't they post examples of their "hand written notes" like they did with the text? Trying to hide their bias once again maybe?
