You can stop your bickering about which Skittles flavor is best, because (spoiler) they all taste the exact same, anyway. So why do we argue that red is best and that we should pick around all the green?

It turns out that our five senses influence each other more than you would think, and scientists are studying the effect sight and smell have on how we taste foods.

Don Katz is a neuropsychologist at Brandeis University and specializes in taste. Speaking with NPR, he recounted an experiment conducted by Charles Spence in the United Kingdom.

Katz says Spence gave a group of college students a row of clear drinks, each with a different flavor -- orange, grape, apple and lemon. The students identified each flavor with ease. But then he added food coloring, mismatching the color with flavor. For example, the grape-flavored drink was colored orange.

"While I wouldn't say they went to chance, their ability to tell which was which got really subpar all of a sudden," Katz told NPR. "The orange beverage tasted orange [to them]. The yellow tasted like lemonade. There wasn't a thing they could do about it."

The students were so influenced by the color of what they were drinking, their brains observed the sensory cue and associated it with what a drink of that color usually tastes like.

It's the same with Skittles.

"The Skittles people, being much smarter than most of us, recognize that it is cheaper to make things smell and look different than it is to make them actually taste different," Katz said. "So, Skittles have different fragrances and different colors -- but they all taste exactly the same."

Though the Skittles manufactures have bamboozled us, not all candies have tricked our senses. HARIBO gummy bears, for example, are all made with five different flavorings.

So the next time you're eating around those green Skittles, just close your eyes and dig in.
