People who prefer to use text messages instead of calls generally have these 3 main qualities

Our smartphones reveal a lot more about ourselves and our habits than we might think. Fully integrated into our daily lives, these devices even allow us to define different user profiles. Are you old-school, using your smartphone only for making calls? Or, conversely, are you more into social media and apps?
According to a recent study by YouGov , nearly 40% of smartphone owners rely more on text messages than calls when it comes to contacting their loved ones. This figure tends to be higher among younger respondents, with almost 50% of 18-24 year-olds indicating they prefer this method of communication.
We've already heard criticisms pointing to laziness, disrespect, shyness, or the difficulty some people have in expressing themselves orally. However, several cross-studies from sites like Jobpal and PsychologyToday assure us that people who prefer using text messages over phone calls generally have several positive qualities.

First, people who prefer texting their loved ones rather than calling them value their free time more. A phone call typically takes much longer than a text message conversation. People who prefer this type of conversation generally feel that text messages are enough to keep the conversation going without having to interrupt their day.
Another great quality of people who prefer texting over calling is that they're excellent communicators. And thoughtful communicators! When someone sends a message, they take more time to think about their response and therefore choose their words more carefully than if they were on the phone. In a verbal conversation, you generally have to respond quickly and naturally, leaving little time to choose words carefully.
Finally, among the qualities mentioned for people who prefer texting to calling is their appreciation for privacy. This information shouldn't surprise you too much, since text conversations are generally much more confidential than phone calls. The latter require you to speak in the middle of everyone around you—at the office, on public transport, in the living room—who are likely to hear your entire conversation. If you prefer texting to calling, it could well mean that you value your privacy and that of others.
