Katy Milkman, PhD, is a professor at The Wharton School of the University of Pennsylvania. She’s also the host of Charles Schwab’s popular behavioral economics podcast Choiceology and author of How to Change: The Science of Getting From Where You Are to Where You Want to Be.
The best-seller describes the little things you can do to make a big difference in your life.
"How did Google become the great[est] search engine? Because it has this very efficient algorithm. It takes the path of least resistance. It looks for a fast solution. And that's what we do too. We prefer to choose the easiest way to achieve any objective," Milkman said.
"Most goals fail. And if you aren't strategizing and making plans and setting goals and figuring out what could stand in your way and using the best science-based strategies, you're not giving yourself the best chance at success."
So, we decided to dig a little deeper and put together a list of psychological "hacks" that people have tested themselves and reviewed positively online.

Best one for kids, and this works wonders for behavioral problems. You never say "don't do x." I had a terror child in daycare and people would yell at him for acting out. I would start each day by saying "You're going to be a good boy today!" And every time he acted out I would say "wait, you're my good boy right?" He would say yes and stop doing it. When his mom came to get him I made a point to of telling her how good he was. That child never acted out around me after a week.

I used the "gray rock" method on my narcissist brother in law.

Basically, I made myself so dull and boring and the opposite of drama that he learned to avoid me at all costs. It worked like a charm, and only took 4-5 encounters to take effect.

If you work with clients, prevent them from getting defensive and angry by not using the word "you".

It's not "you didn't send the attachment", it's "the attachment didn't send". Don't blame them, blame the thing you're talking about.

I take my time when I write emails to clients because I like to word things *just* right...one word can be the difference between a happy client and an unhappy one. The right words in the right order can influence people to make decisions you want them to make. Words are powerful.

The concept of getting something for free completely derails a person's critical thinking skills.

My dad was tool distributor and drove a truck to various repair shops selling tools to mechanics.

He got an idea to start selling candy bars on his truck for one dollar. But you would get a free candy bar with every tool purchase.

Almost everyone who asked how much the candy bar was didn't want to pay a dollar for one, but they would buy a $100 socket set in order to get the candy bar for free.

In an argument speak softly. It forces active listening which leads to active thinking. When they are listening and thinking they are not yelling, arguing, or talking.

You want someone you just met to like you? Ask them open-ended questions about themselves. Don't wait for your turn to speak. Listen, and then ask a follow-up question based on what they said. If you do that a couple of times, that person feels heard and appreciated by you. If they realize they're doing all the talking, they'll apologize and ask a question of you. If your answer is short and pivots back into something they said, you have now formed a connection in their mind as a good listener who is interested in what they have to say. People like that a lot.

Does this count...? They aren't cool, but pretty helpful.

I sometimes have anxiety brain where I start to panic about the future or the past or whatever. I've learned to stop myself, and tell myself: "Hey, wait, you need to finish your job. Your job is...xxx"

So, for instance, I'll be doing dishes, get lost in thought, and start to get upset and anxious. I'll then tell myself, "hey, you have to finish doing the dishes, that's your job right now." And then I'll take a deep breath, or multiple deep breaths.

It's just another way to center yourself and bring yourself back to the present, but it's helpful. Hard to do it at first, but I've gotten good at it.

Also, sometimes anxiety brain can lead to some heavy, self-loathing, probably false thoughts. I've more recently taught myself that when that happens to stop, take a breath, and say one nice thing about myself.

So when bad brain goes into: "What the f**k Tammy Tangerine, you're the worst, I can't believe you f****d up that insignificant thing", I'll try and stop myself and say something like, "f**k that, no, I am kind."

That's a harder trick for sure, but I'm getting better at it.

If you have trouble motivating yourself to do something like learn a skill (instrument, language etc.) tell yourself "Ok, I'll sit down and do this for just five minutes"

A lot of the time you'll end up going for much longer than five minutes, but even if you don't it's still five minutes of practice in whatever the heck you wanted to learn in the first place.

Giving students in my elementary class the illusion of choice. If you ask "do you want to start your work?" Or "isn't it time we got something done?" I modify it to-

"Would you like to do your assignment with a pencil or blue pen?" They are too consumed with this choice that they have forgotten that they didn't want to do it in the first place.

Also, every recess-

"Did you push jimmy?" "No."

"Ok umm two people saw you do it, and reported it to me. Are you sure you didn't?" "In sure."

Then change it to "can you tell me *why* you pushed him?"

"Well it's because..."

Gets'em every time.

When you're walking through a crowded hallway, if you keep your eyes focused in the exact direction you're going, people will naturally clear out of your way because we sub-consciously use eye-contact with people in order to navigate around each other.

Have a toddler that is in a bad mood? Sit down with them, look them straight in the eye, and say "You're mad, so don't laugh." Just keep repeating it as seriously as you can.

I've done it for 15 different cousins over a couple of decades, and by the fifth repetition of "DON'T LAUGH" they are busting a gut and rolling on the floor.

If someone won't stop talking or let you get a word in, drop something (keys, pen). Reach down to pick them up and start talking. It's a way to interrupt without the other person realizing it.

When someone asks me a question that I don't want to answer, I *always* say "Why do you ask?" It's my go-to.

If someone is talking or preoccupied, you can hold out your hand and they'll give you whatever they're holding. I did it to my sister with the car keys and made her think she lost them somewhere at the store.

My favorite is silently maintaining eye contact when a person is attempted to bargain or convince you of something that you don't want to do, or don't believe.

They usually end up negotiating with themselves (which gives you a huge advantage because once that happens, it is pretty much game over).

One of my friends was taking Psych 101 in college, and she referenced something called "confusing". The example was to use a word or phrase out of context as a means to diffuse a situation.

Our Boss (who was always kind of a jerk to her): WHY WERE YOU LATE TODAY?!?

My friend: Oh, my goodness! Traffic was so *armadillo!* I'm so very sorry!

Our Boss: Um, okay...don't let it happen again.

The Flinch. Whether you're negotiating a raise, the sale price of a car you want to buy, who does what chores around the house, always flinch visibly at the first and sometimes second offers. The Flinch can be as simple as a small wince, a sigh, or an eyeroll. The Flinch quite often causes people to lowball the initial offer. I learned this from my was-husband and it freaking works. Got my current job at 10% over the max salary because I flinched.

When you're talking to someone who's being defensive and there is a pause in the conversation, let them fill it.

Anonymous: They'll incriminate themselves.

I don't know if this fits but when a kid gets hurt a little and all the adults start freaking out the kids gonna f*****g cry. Tell the gullible little s**t "Oh, you're fine. You're not hurt." For little things, like a scraped knee, it's worked like a charm for me at keeping them happy. For serious injuries it can help them to keep calm. Nothing tells a kid that everything is wrong and they're gonna die like all the adults around them acting like it.

edit: Yeah, yeah, maybe I shouldn't tell a kid what to feel and maybe I shouldn't invalidate their feelings. Like I give a f**k, I'm not the bloody parent. I just hate the wailing of children and this is my **trick** to get them to stay relatively quiet. The question was "What are the coolest psychology **tricks** that you know or have used?" not "What parenting strategy should everyone try out?".

The Primacy Effect (you're more likely to remember the first item on a list) and the Recency Effect (you're more likely to remember the last item on a list).

If I'm listing groceries for my husband, I make the most important items into bookends. If I'm talking to the parent of one of my students about their kid's behaviour, I always list good, bad, good. They get the information about the bad, but what they remember about the conversation is how they felt good and saw that I care about their kid.
