A study of environmental behavioral nudges

Nudging for the Environment Recycling rates can be increased by 34 percent simply by matching the shape of lid of the recycling bin to the shape of the object to be recycled: Nelda, Stacy Guidry, Levi Lainhart.

Psychology Matters We are remarkably social creatures, evolutionarily tuned to our local environments to an extent we rarely appreciate. Additional co-authors on the paper include Cass R. Each of those makes the customer aware that some sort of intervention is happening. But the new findings clearly show that nudge-type strategies based in behavioral science do offer a useful, low-cost approach to promoting behaviors tied to a variety of important outcomes.

The drive toward the social norm can push either toward or away from pro-environment behavior.

Behavioral ‘Nudges’ Offer a Cost-Effective Policy Tool

The new study, which examined the cost-effectiveness of nudges and typical intervention A study of environmental behavioral nudges like financial incentives side-by-side, found that nudges often yield particularly high returns at a low cost when it comes to boosting retirement savings, college enrollment, energy conservation, and vaccination rates.

In each of the domains that the researchers examined, nudges were highly cost effective, often more so than the traditional policy interventions.

When customers got both a reflective placard in the cart and arrows on the floor, they bought less produce.


The program will affect over 20, state employees, providing them recycling bins with attachable mini-bins for garbage. Reducing the cognitive demand required leads to increased compliance. However, when customers whose energy use was below average got a smiley-face with that news, the emoticon prevented the subsequent increase.

Thus, nudges may be especially useful in guiding behavior when people are making decisions in less than ideal circumstances, such as when they are busy, tired, or otherwise not able to fully engage with the choices available to them. Austin will roll out an even smaller garbage bin gallon soon.

Nudging environmental behavior

The results showed a A study of environmental behavioral nudges Policies that ignore the nuances of human psychology, that assume Homo sapiens and Homo economicus are roughly the same beast, will never reach their hoped-for level of impact.

The smaller the bin, the less the resident pays. When energy bills included a comparison to average use for the neighborhood, customers who had used more than average decreased their use, while those who had used less than average increased their use.

The New York Times recently highlighted interesting research on nudging consumers to healthier food purchasing decisions. A gallon bin cost about twice the price of the smallest gallon bin. To increase recycling rates in an office environment, where the vast majority of refuse is recyclable, the small size of the mini-bin acts as a visual yield sign for employees when they discard something.

Clearly, nudges can effect powerful changes in behavior. The blue bin is a lot bigger. As such, they may be overlooked as useful policy tools despite their relatively low cost.

Recent research suggests it would. The blue bin is for recycling; the green bin is for garbage. On the other hand, policy makers who engage with behavioral science will find low-cost, low-opposition measures that are often jaw-droppingly effective. The recycling-bin-to-garbage-bin ratio in Austin stands in stark contrast to ratios in most American cities.

The program allows residents to choose the size of garbage bin that best fits their needs. By Michael Levy - Posted on 13 September Would this grocery cart, outfitted with a reflection of your face, make you buy more produce?

Looking at the reports from the SBST and the UK Behavioural Insights Team, the researchers developed a list of relevant policy areas and identified one behavior as the outcome of interest within each area. But by putting big green arrows on the floor, the same researchers were able to direct 90 percent of shoppers to disregard their norms and habits and head left for the produce isle.

May 2, in Blog posts 14 comments The photo above comes to us from Austin, Texas. TFC explains the program: Unlike traditional interventions that are designed to influence the cost-benefit calculations that people make, nudges harness decision-making processes that operate automatically.

For example, Alexandria, Virginia, provides residents with a garbage bin shown below that is nearly three times the size of the recycling bin. Nudging Nudging refers to effecting desired behaviors through subtle changes to the context in which the decision is made.

The findings are published in Psychological Science, a journal of the Association for Psychological Science. And there are many cases in which traditional tools — such as prohibitions and mandates — are essential for achieving specific policy objectives, and nudges might not be of value.

So as you go about your day, remember that every day, more people are doing what they can to protect our environment. This article has received the badge for Open Materials. With this in mind, a research team including academics and practitioners inside and outside of government examined existing studies to evaluate the relative cost effectiveness of nudges and other policy interventions.Behavioral nudges in competitive environments: a field experiment examining defaults and social comparisons in a conservation contract auction1 Draft – June 1, This study explores this question through a field experiment in which farmers from Texas, Delaware, and Maryland compete in an auction of conservation contracts that require.

Behavioral nudges lead to striking drop in prescriptions of potent antipsychotic The study was a randomized controlled trial targeting the. Nudging environmental behavior.

On the other hand, policy makers who engage with behavioral science will find low-cost, low-opposition measures that are often jaw-droppingly effective.

Nudging. Clearly, nudges can effect powerful changes in behavior. However, they have to be implemented with an appreciation for nuance. Governments around the world have increasingly turned to behavioral science to help address various policy problems – new research shows that some of the best-known strategies derived from behavioral science, commonly referred to as ‘nudges,’ may be extremely cost effective.

The new study. This study explores two examples of behavioural environmental economics: green nudges and corporate environmental strategies. Our unit of analysis was a single intervention within a study; by intervention, we are referring to a treatment and its measured impact on a unique behavioral outcome.

For experiments that measured multiple behavioral outcomes (eg used contraception and reduced sexual activity), each behavior counted separately.
