I was witness to a tricky marital exchange last week, when my sister and her husband were trying to name their new red Labrador puppy.

Rachel had spent hours trolling for ideas on the Internet and polling friends and family. Days later, she had dozens of monikers in the running—Valentino, Fonzie, Holden, Simba, Brandy Junior (named for our beloved childhood spaniel) and Olivia Newton John (don’t ask).

Finally, Rachel’s husband, J.J., interrupted: “Let’s just call him Jimmy.”

Psychology researchers have studied how people make decisions and concluded there are two basic styles. “Maximizers” like to take their time and weigh a wide range of options—sometimes every possible one—before choosing. “Satisficers” would rather be fast than thorough; they prefer to quickly choose the option that fills the minimum criteria (the word “satisfice” blends “satisfy” and “suffice”).

“Maximizers are people who want the very best. Satisficers are people who want good enough,” says Barry Schwartz, a professor of psychology at Swarthmore College in Pennsylvania and author of “The Paradox of Choice.”
