I’ve spent most of my profession thus far investigating one phenomenon: the tendency for individuals to want smaller, sooner rewards over bigger, later rewards. This tendency is named temporal discounting. Each time I’ve described it to individuals, they often nod their heads knowingly and share examples: having an additional slice of cake (regardless of understanding it is going to make them really feel dangerous later), spending cash on enjoyable luxurious objects (as an alternative of saving it for retirement), paying further to get their objects shipped sooner, and many others.
So, I all the time assumed that temporal discounting–which I can even seek advice from as impatience – was a common, human phenomenon, though not everybody “reductions” the longer term to the identical diploma. However not solely do I dwell in a WEIRD (i.e., western, educated, industrialized, rich, and democratic) society, however I (like many others) additionally are likely to do analysis in WEIRD samples. That implies that there was all the time a risk that temporal discounting is a WEIRD quirk that may not be generalizable to totally different cultures.
That’s why a current examine, titled “The Globalizability of Temporal Discounting” is such a giant deal. 170 authors, led by Kai Ruggeri from Columbia College, assessed temporal discounting in over 13,000 topics from 61 international locations, and so they discovered that, yep, temporal discounting is noticed in all these international locations.
Topics have been requested questions like, “Do you favor $500 now or $550 in 12 months?” to see how a lot they must be provided in a single 12 months with a view to hand over a smaller quantity now (observe: financial quantities have been adjusted for foreign money and buying energy).
It seems that everybody prefers rewards sooner quite than later, even when the later reward is bigger. Actually, individuals’s preferences differed extra inside international locations than they did between international locations. Temporal discounting is not only generalizable; it’s “globalizable.”
Listed below are a few different fascinating findings from the paper, and my takes:
Folks from poorer international locations (with extra financial inequality) are extra impatient. The wording right here is vital. It isn’t the case that poor persons are extra impatient. Actually, the authors discovered no relationship between somebody’s financial standing of their nation and their degree of temporal discounting. As an alternative, evidently financially unstable environments–marked by excessive inflation, excessive inequality, and decrease wealth–can foster extra impatience. Though not allocating assets for the longer term may be problematic (e.g., resulting in low financial savings and poor well being), it’s value stating that this seemingly short-sighted conduct is definitely rational when issues are unpredictable.
For instance, if inflation is excessive and may worsen, perhaps that $550 in a single 12 months is not going to really be value as a lot as $500 now. And the longer term is all the time unsure, however in poorer international locations that uncertainty may be magnified. When you actually consider {that a} “chook within the hand is value two within the bush,” then temporal discounting makes an entire lot of sense: take the $500 now in case the $550 by no means comes alongside.
“Current bias” won’t be as pervasive because it appears. Okay, I’ll admit this takeaway is my very own quite than the authors’. Along with testing how a lot individuals discounted future rewards, the authors additionally requested about different head-scratching phenomena associated to temporal discounting, often called anomalies. Anomalies are patterns of conduct that don’t make a lot financial sense, however have been noticed in a whole lot of research. I don’t have house right here to debate all of them, so I’ll simply discuss a controversial one which I discover fascinating: current bias.
When you want to have $500 now over $550 in 12 months, then you definitely must also want to have $500 in 12 months over $550 in 24 months, for the reason that period of time between the 2 choices is similar in each circumstances (12 months). Nevertheless, many individuals change their preferences, preferring $500 now over $550 in a single 12 months, however really preferring $550 in two years over $500 in a single 12 months. This anomaly has been known as “current bias,” as a result of it means that there’s something about having cash now that makes it particularly invaluable.
The Ruggeri et al. (2022) examine discovered that current bias can be not simply reserved for “WEIRD” samples; individuals in all international locations displayed this bias. Nevertheless, I seen that solely about 13 p.c of every nation’s pattern confirmed the impact, making it not practically as widespread as temporal discounting itself.
One other compelling tidbit within the paper is that folks in wealthier international locations confirmed current bias extra than individuals in poorer international locations did, at the same time as they have been typically extra affected person. Whereas these findings are secondary to the primary end result–that neither temporal discounting nor its associated anomalies are distinctive to our tradition–it’s positively worthy of extra exploration.
Total, the Ruggeri et al. examine is actually a feat of contemporary science. Bringing collectively 170 researchers in 61 international locations to conduct the identical protocol in 13,629 individuals (throughout a worldwide pandemic, no much less!) is astounding. I’m so joyful to witness this degree of cooperation all within the identify of studying the reality in regards to the psychological tendencies that unite us all.
