7 Days of Intentional Kindness

Editor’s Note: Our friends at Kindness.org have been doing some fascinating work on the “science” around kindness. They’ve graciously allowed us to reprint this article about one of their studies. We can all learn from it!

If you’ve ever experienced a moment of unexpected kindness when you’re feeling down, it seems obvious that kindness is a good thing. But why, exactly, is it a good thing? Scientific inquiry allows us to find answers that can be tangibly measured.

As we took a close look at the meta-analysis of kindness we commissioned from Oxford University, kindness.org began to explore the improvements in emotional wellbeing that result from carrying out kind acts. We continued to look at the positive mental and emotional effects of carrying out kind acts with our very first kindlab experiment.

Our hypothesis

The overwhelming majority of studies in kindness scientific literature do not distinguish between different types of kindness, delivered by different kinds of people to different kinds of recipients. While the research shows that kindness has positive effects, we don’t really know when they are largest, and we don’t know what types of kindness best achieve these effects.

Could we determine if there are any kindness group differences in post-intervention wellbeing? Does being kind to family and friends boost wellbeing more than being kind to strangers (or the other way around)? Does acting kind boost wellbeing more than observing kindness?

This is the first study of its kind to investigate these questions in a single experimental design. We are grateful to the hundreds of people who took part.

Our 7-Day Kindness Intervention Study

Volunteers were randomly assigned to a kindness group (i.e. they carry out acts of kindness for a period of time), and other volunteers were assigned to a control group (i.e. they do not carry out acts of kindness). The volunteers, or participants, were tested before and after the intervention period, and any noticeable change in the before and after tests is attributable to the effect of the intervention.

In our study we included four ‘kindness’ groups:

Familiars Acts of kindness were carried out on family and close friends

Strangers Acts of kindness were carried out on strangers or people who are very loosely known

Self/Novel Acts of kindness were carried out on oneself, and involved doing something atypical

Observers Acts of kindness were not carried out, but participants were required to observe other people carrying out acts of kindness

The study also included a No-Intervention Control group so that we could compare the effect of the kindness groups with a group that did not perform or (purposefully) observe any kindness.

There are several reasons for supposing that the emotional effects of kindness may be affected by who the act of kindness is delivered to.

For instance, some people may get more of an emotional buzz from being generous to someone in need (e.g. a homeless person) than to someone who is ungrateful. On the other hand, we may get more emotional reward from being kind to someone who is close to us versus someone who we do not know (research on strong and weak ties by Laura Aknin and colleagues seems to support this; Aknin et al. 2011).

To address this problem, we were very deliberate in how we defined the groups who participated in our study.

The Familiar and Strangers groups were included to investigate whether acts of kindness to people we know versus people we do not know have differing effects on emotional wellbeing.

The Self/Novel group was included for two reasons. The first reason was to see if we could detect any effect of being kind to oneself (versus being kind to others) on wellbeing. Secondly, we wanted to control for acts of novelty, as doing new things for ten days has been shown to elicit comparable levels of life satisfaction as does doing acts of kindness for ten days (Buchanan and Bardi, 2010).

The Observers group was included because evidence shows that recalling acts of kindness (that is, thinking about past kindness, rather than actually doing kindness during the study) has an effect on wellbeing. We thought it would be interesting to see if simply observing kindness would have a positive emotional effect.

Our method

After the 7-day kindness intervention, participants completed a post-intervention version of the questionnaire that asked about the same social and emotional constructs.

We then used statistics to test for changes in scores before and after the intervention.

In summary, our study sought to test the emotional effects of kindness to friends and family, kindness to strangers, kindness to self through novel behaviors, and observing acts of kindness, and to compare against a non-intervention control group that was not instructed to engage in seven days of kind acts.

The kind acts

At the end of the day an email was sent asking participants to indicate how many (and which) acts of kindness they had carried out that day.

We specifically selected acts based on affordability, ease of opportunity, and commonality. Overall twenty-one acts were offered so that all participants could find something suitable and achievable. We wanted people to have a choice of kind acts — and some flexibility in how they were performed — as research has shown that autonomy is an important factor in the relationship between kindness and wellbeing (Nelson et al. 2015).

What does our study show?

We also found that the degrees of change in wellbeing and social perceptions were dependent on the number of acts completed — that is, the more you engage in kindness, the greater your wellbeing, compassion, trust, positivity about humanity, and connection.

The changes are small, but robust. Here is a breakdown of the data and statistics from our study.

Demographics

The majority of the participants were female (88.4%) but we also had 9.9% male, 1.5% who preferred not to say, and .2% gender fluid. They were from a wide age range with 67.0% between 30–59 years of age, 20.3% 13–29, 12.7% 60+. 28% were from the kindness.org community, and 72% signed up via social media.

Positive effects of kindness for each group in the study

Within the context of this study, kindness to family and friends, strangers, self, and observing kindness, had equally positive effects on wellbeing and positive social emotions.

The table above shows the mean scores (maximum possible score = 10.0) for the emotional wellbeing (happiness, life satisfaction, compassion) and positive social emotions (trust, positive about humanity, and connection) measures. It is clear that each measure increases over the course of the study (from pre- to post-intervention).

Methods of analysis

The more kind acts completed, the greater the effect on wellbeing

We ran an analysis to see if the number of kind acts completed over the course of the week had any effect on wellbeing. We found that it did. The table above shows the mean happiness scores across different numbers of kind acts. The same pattern of results was found for all the post-intervention measures, and all were statistically significant.

Unexpected developments and challenges

There are several possible reasons for these unexpected results. First, we did not require participants in the Self Novel and Observers groups to refrain from carrying out acts of kindness to family, friends, or strangers over the study period. Any changes in our measures could simply have been due to additional kindness on top of the ‘self’ and ‘observed’ acts we asked them to complete. In fact, it is likely that being unusually kind to yourself or attuned to others being kind, causes you to be kinder than usual in your day-to-day life. Unfortunately, we cannot know, as we did not test for this possibility.

A second challenge is that we had a very pro-kindness sample. Participants volunteered from our kindness community as well as people who follow us on social media — and their social network. Therefore, changes in wellbeing and positive social emotions may have been small because our sample was already high on these measures to begin with (because this audience may be kinder than average).

Another possibility is that asking a pro-kindness sample to engage in a kindness intervention may not have altered their typical kindness levels by much. Kindness levels for our sample changed very little over the study period. Therefore it’s not surprising that wellbeing didn’t change by large amounts. It’s perhaps remarkable that it changed at all, and is a testament to the effectiveness of kindness interventions for improving wellbeing and positive social emotions.

Where do we go from here?

We had hypothesized that the kindness interventions would boost wellbeing and positive social emotions, and that is exactly what happened. Our analysis also showed that the greater engagement in the study (i.e. the number of kind acts completed), the greater the positive change in our measures of happiness, life satisfaction, compassion, trust, positivity about humanity, and connection. These are encouraging results that bode well for the future.

We’ll be designing our second kindness study soon. Our aim will be to improve on and extend this study to further explore the science of kindness.
