Are distractions are Habitual ? Do we long for distractions ?

From "The power of habit" by Charles Duhigg. In the course of explaining how habits are formed, there was a sentence to this effect: "In an experiment to study habits, monkeys were given a drop of juice (reward) everytime they completed a particular task, say clicking a yellow button on the screen ( trigger). After few trials, the monkeys' brain started longing for the reward as soon as the trigger appeared. In exactly similar pattern, human brains are now rewired to long for the momentary distraction from the current task ( reward) everytime the phone beeps or when the notifications (trigger) arrive" So is our tendency "to get distracted" habitual ? Could this be true ? I decided to block all notifications (triggers) in the last 5 days and decided to check my phone hourly. Here's the result : My battery that read 16-18% at end of the day, now reads 40% at the end of the day. Indicating the reduction in screen time - the time I saved , by avoiding those useless notifications (Like LinkedIn notifying me of the daily news rundown, WhatsApp notifying me of the countless forward messages,or Facebook notifying me of friend suggestions or emails from a list you subscribed a millennia ago).

True - Notifications are the new time and productivity killers ! Do you agree ?
