In Aziz Ansari's book, Modern Romance, he explores the different struggles of dating and shares a bit of his experience. BUT he also gets down with science and helps explain some of our modern problems in terms of psychology.
One of the things he covers is texting back! It's been a struggle for a lot of us, knowing when or how to respond.
His suggestion: Don't respond right away! Here's how he explains it using science!
"In recent years behavioral scientists have shed some light on why waiting techniques can be powerful. If a text back from someone is considered a “reward,” consider the fact that lab animals who get rewarded for pushing a lever every time will eventually slow down because they know that the next time they want a reward, it will be waiting for them. So basically, if you are the guy or girl who texts back immediately, you are taken for granted and ultimately lower your value as a reward. As a result, the person doesn’t feel as much of an urge to text you or, in the case of the lab animal, push the lever."
Essentially: Rewarding the person on the other end of the phone with a text back so fast is viewed as less exciting or valuable after a while.
Personally, I'm one to respond when I'm free. So if I take a little while to respond, it usually means I'm busy. But if I respond right away, it means you texted me at a good time. My suggestion: respond back when you are free, and don't take science too seriously;)
