A neuroscientist suggests that a straightforward technique can significantly enhance your decision-making abilities, according to research.

Research indicates that it is more challenging to solve problems or answer questions when there are more than four possible solutions. We often become overwhelmed and lose focus when comparing all options, even if we already know the best answer.

To make smart decisions consistently, neuroscientist Paul Glimcher suggests choosing the worst option first instead of trying to select the best one.

According to Glimcher, a professor at New York University, when presented with six candy bars, your favorite candy may not send as strong a signal to your brain due to the presence of other options. However, if you are asked to remove the worst candy bar, your confidence in selecting the best option will increase as you move towards the next-worst candy bar.

The process of elimination is a familiar concept that can aid in making accurate decisions and avoiding errors in daily life, according to Glimcher.

To avoid choosing a restaurant you don't enjoy when a friend sends you a list of options for a night out, consider eliminating the least useful data points at work when selecting which ones to highlight in a presentation.

"Glimcher stated, "We excel at binary choice tasks, selecting the best and discarding the worst. However, in today's world where companies offer numerous options, it significantly impacts our performance.""

Glimcher stated that selecting from fewer options can aid in making more accurate decisions. However, his research also indicates that this process may slightly increase decision fatigue, as it takes longer and results in more decisions to make, despite the ease of each choice.

To combat fatigue, experts suggest making decisions earlier in the day when you have more mental energy and developing routines to make some choices feel like habits, rather than requiring analysis.

Using a similar strategy can help you be more persuasive, too

Being aware of choice overload can help you persuade others during conversations or debates, according to Niro Sivanathan, an organizational behavior professor at London Business School, who shared this insight in November with CNBC Make It.

""Oftentimes, things fail not in content, but delivery," he said."

Sivanthan stated that when making an argument, it is more effective to focus on one or two strongest points rather than presenting five reasons why you are right. People tend to remember the overall persuasiveness of an argument rather than the single most compelling point made during it.

"One key argument is enough," he said. "Be confident and present it, rather than feeling the need to list many others."
