Here that same Google design ethicist explains in detail how technology hijacks your mind [1].

TL;DR:

Hijack 1: If You Control the Menu, You Control the Choices. Ask yourself: What’s not on the menu?, Why am I being given these options and not others? Do I know the menu provider’s goals? Is this menu empowering for my original need, or are the choices actually a distraction?

Hijack 2: Make apps behave like Slot Machines - give a variable reward. If you want to maximize addictiveness, link a user’s action (like pulling a lever) with a variable reward. You pull a lever and immediately receive either an enticing reward (a match, a prize!) or nothing. Addictiveness is maximized when the rate of reward is most variable.

Hijack 3: Fear of Missing Something Important (FOMSI). If I convince you that I’m a channel for important information, messages, friendships, or potential sexual opportunities — it will be hard for you to turn me off, unsubscribe, or remove your account — because there is a 1% chance you could be missing something important.

Hijack 4: Social Approval. When you get tagged by my friend, you think s/he made a conscious choice to tag you, when actually s/he just responds to Facebook’s suggestion, not making an independent choice. Thus Facebook controls the multiplier for how often millions of people experience their social approval on the line.

Hijack 5: Social Reciprocity (Tit-for-tat). You follow me — it’s rude not to follow you back. When you receive an invitation from someone to connect, you imagine that person making a conscious choice to invite you, when in reality, they likely unconsciously responded to LinkedIn’s list of suggested c ontacts.

Hijack 6: Bottomless bowls, Infinite Feeds, and Autoplay

Hijack 7: Instant Interruption vs. “Respectful” Delivery. Messages that interrupt people immediately are more persuasive at getting people to respond than messages delivered asynchronously.

Hijack 8: Bundling Your Reasons with Their Reasons. When you you want to look up a Facebook event happening tonight (your reason) the Facebook app doesn’t allow you to access it without first landing on the news feed (their reasons), so Facebook converts every reason you have for using it, into their reason which is to maximize the time you spend consuming things. In an ideal world, apps would always give you a direct way to get what you want separately from what they want.

Hijack 9: Inconvenient Choices. Businesses naturally want to make the choices they want you to make easier, and the choices they don’t want you to make harder. NYTimes.com claims to give you “a free choice” to cancel your digital subscription. But instead of just doing it when you hit “Cancel Subscription,” they force you to call a phone number that’s only open at certain times.

Hijack 10: Forecasting Errors, “Foot in the Door” strategies. People don’t intuitively forecast the true time cost of a click when it’s presented to them. Sales people use “foot in the door” techniques by asking for a small innocuous request to begin with (“just one click”), and escalating from there (“why don’t you stay awhile?”). Virtually all engagement websites use this trick.
