Physicist Albert Einstein famously posited that if he solely had an hour to crack a frightening drawback, he’d commit 55 minutes to understanding it and solely 5 minutes to crafting an answer. Einstein believed that essentially the most troublesome facet of problem-solving was gaining a complete grasp of the problem to be addressed.
That viewpoint has been corroborated by a College of Miami Patti and Allan Herbert Enterprise College economist who co-created a cell phone app that collected knowledge from greater than 7,000 take a look at topics scattered across the globe.
Alex Horenstein, affiliate professor within the Division of Economics and affiliate dean of undergraduate enterprise research, teamed with HEC Paris economist Konrad Grabiszewski to create an attractive cell technique sport, Blues and Reds, that doubled as a complicated behavioral experiment. An article about Horenstein’s venture, “Understanding Dynamic Interactions,” was revealed by Video games and Financial Habits, a general-interest journal dedicated to sport idea and its functions.
“The venture confirmed that, more often than not when individuals attain the incorrect final result, it is not as a result of they do not know how you can resolve issues,” Horenstein noticed. “It’s as a result of they don’t perceive the issue they have been supposed to resolve.
“For instance, if you happen to say I wish to go from Level A to Level B and you do not have in mind that one of many streets that you simply plan to take is one-way, in your head you may need solved the proper drawback, particularly, “Which is the shortest path to take?'” mentioned Horenstein. “However you discovered the answer to the incorrect drawback, as a result of in your shortest path, you assumed a one-way avenue was two-way.”
The genesis of Blues and Reds stems from a 2015 Metrorail experience Horenstein took from Coral Gables to Brickell with Grabiszewski. They have been colleagues at Miami Herbert on the time and through their northerly Metrorail trek, each economists seen that the majority of their fellow commuters have been glued to their cellphones.
“Persons are interacting with the actual world via their telephones,” Horenstein recalled pondering throughout the Metrorail experience with Grabiszewski. “So, we requested ourselves: ‘Why do not we create an experiment that takes place proper within the cellphone, in an setting the place persons are already snug interacting?'”
Set within the iPhone/Android area, that is a staple of recent life. Blues and Reds current the identical strategic issues to gamers, however in numerous codecs. One model lets gamers see the whole sport construction laid out like a standard resolution tree, to incorporate all potential strikes and potential outcomes.
Within the second model, gamers get the identical data, however must assemble a choice tree on their very own. Connections between selections and outcomes aren’t delineated and have to be found out. The non-tree iteration requires doing the extra cognitive work of understanding the issue construction.
“One of many vital issues about Blues and Reds is that it’s proposing a brand new option to conduct experiments, with out necessitating a bodily lab or direct interaction with the members,” Horenstein mentioned. “Blues and Reds provides you entry to a really wealthy dataset, and it lets you collect knowledge on a worldwide foundation.
“We now have knowledge from 1000’s of individuals in additional than 100 nations, which is difficult—if not unattainable—to do in a lab setting at a college.”
Horenstein added that to the very best of his data, Blues and Reds was the primary cell phone app designed particularly to conduct analysis in economics.
Though the Blues and Reds app is now not energetic—it was retired after the info assortment section completed—the venture stays a pioneering instance of how mobile technology can be utilized to conduct large-scale behavioral experiments.

Evaluation of knowledge from a cell technique sport involving over 7,000 members worldwide signifies that failure in problem-solving is extra usually on account of misunderstanding the issue quite than incapability to resolve it. When gamers needed to deduce the issue construction themselves, efficiency declined, highlighting the essential position of drawback comprehension in attaining appropriate options.
