For a long time, retirement followed a pretty familiar script. Work for decades. Retire around 65. Slow down. Enjoy a quieter chapter.

But that version of retirement was built for a very different time.

In 1950, U.S. life expectancy was roughly 68 years. Today, retirement can stretch across decades, and many people are asking bigger questions about what this next chapter could actually look like.

Do you know who's listed as the beneficiary on your retirement accounts right now? Not who you'd like it to be — who's actually on the form. Many Americans have never updated theirs. And in many cases, those forms don't follow your will. They supersede it.

What do you think it would take to make better—or even perfect—financial decisions?

More information or more time? Even with that, you can also use less to do more with your money. And that means less bias when it’s time to make key financial decisions.

Our feelings, muddled memories, and even faulty reasoning can all nurture our biases. So can our fears and “intuition.” Still, with a little understanding of those biases, we can start to break free of them.
