These 6 TED talks have completely changed how I make decisions

Big or small, decisions aren't as easy as they may seem.
Psychologists have found decision-making is fraught with hidden influences, tricky nuances, and the ability to make us happy in the short-term but unhappy in the long-term.

Some of my greatest insights into this aspect of human behavior have come from TED talks, which break down research findings into their most digestible form.

Here are the talks that have changed how I make decisions.

"How to make hard choices"

Philosopher Ruth Chang's 2013 talk explains that people often struggle to choose between two equally good options that are "on a par."
People tend to view hard choices as burdens, but Chang would prefer we see them as blessings that grant us agency. Hard choices make us confront our desire to live in the city over the country, for example, or to eat a healthy breakfast over sugary cereal.

The takeaway: Whenever I face a hard choice, I celebrate it as a way to cement an aspect of my identity.

"Grit: The power of passion and perseverance"

In 2013, UPenn psychologist Angela Duckworth presented the findings of her research on grit — or the ability to keep trucking when life gets hard.
Duckworth has found across numerous fields that grit is the single-biggest indicator of personal and professional success, even more than IQ. And the best way to cultivate grit is to build a "growth mindset" that sees circumstances are flexible, not rigid.

The takeaway: The moment when things start getting tough is the starting point for success, not a sign to call it quits.

"The paradox of choice"

The takeaway: The moment when things start getting tough is the starting point for success, not a sign to call it quits.

"Are we in control of our own decisions?"

Behavioral economist Dan Ariely gave a talkin 2009 that suggests outside forces quietly nudge people toward certain outcomes over others.
A famous example is organ donation. Some countries have far higher rates simply because the form people fill out is opt-out, and people generally stick with the default option.

The takeaway: I do my best to take will power out of the equation by making the default option the healthiest, such as not buying junk food at the store rather than avoiding it in my cabinet every day.

"The surprising habits of original thinkers"

UPenn psychologist Adam Grant remarked in 2016 that some of history's most original thinkers organized their time in interesting ways to achieve maximum creativity.
Specifically, Grant says people should put off their projects for a bit so they can let disparate ideas congeal into something original. It's not quite procrastination, because it's intentional, but it comes close.

The takeaway: If I want to solve a creative problem, the decision to leave and come back to it really does pay off.

"The riddle of experience vs. memory"

Psychologist Daniel Kahneman spoke in 2010 about the two ways we find happiness: in the moment and in our memories. People must keep each in mind when trying to create happiness.
For example, according to Kahneman's research, the experiencing self is twice as happy on a two-week vacation over a one-week vacation, but the remembering self isn't, since no new memories are being formed.

The takeaway: I can make more intentional choices in the service of both selves, in order to maximize each kind of happiness.
