Behavioural Insights and Crime: Part I

Violence against Women (VAW)

When you think of BI and crime, shows like Criminal Minds and Mindhunter (both of which the author of this blog post highly recommends) come to mind. However, tackling VAW requires more than psycho-analysing perpetrators. This is because there are a multitude of other factors leading to the creation of a climate of acceptability toward VAW. Here are some examples, drawing largely on a report by the European Commission:

  • Victims of violence may not report the crime: They may be afraid of the perpetrator, believe they are unlikely to receive help or simply because they are not aware of the support services available. It is also possible that a status quo bias is at play here; victims may be inclined to accept the situation and be unwilling to change it. Social norms could also prohibit them for speaking up.
  • Bystanders may not intervene: Either because they believe it is not their responsibility or that violence within couples is a private matter. They may also lack self-efficacy, i.e. confidence in their ability to make a difference.
  • Perpetrators may not believe they committed a crime, or think they can get away with it. They may also be present biased about the effects on the victim as well as implications for their own lives (punishment/ imprisonment)
  • Disagreement on definitions: For example, while most people agree that rape is wrong, there may not be a consensus on what exactly constitutes rape.
  • Professionals within the legal system may have prejudices too, creating an environment that is not supportive for victims to come forward.
  • Stereotyped media portrayal or inappropriate reporting by journalists of news regarding VAW.

The list is endless and usually a combination of factors operates to encourage victim blaming attitudes. Which is why in the mid-1990s, the causes of VAW were recognised to be probabilistic rather than deterministic. That is to say there is no single cause; the same outcome (VAW) can be caused by a different amalgamation of factors in different social contexts.

One of the simplest models for analysing behavioural causes for a certain action is the Theory of Planned Behaviour. It states that for someone to perform a given behaviour, the following 3 conditions have to hold (assuming they have the intention to carry it out):

  1. Holding a positive attitude toward the behaviour
  2. Considering the behaviour to be in line with social norms
  3. Having self-efficacy i.e. believing that they are able to perform the behaviour

How does BI fit in?

The aforementioned examples can be viewed in light of the above model to design programmes for changing attitudes and behaviours. Some behavioural levers that can be used for this purpose are:

  • Using social norms:

Example: In 1999-2000, James Madison University (JMU, United States of America) ran a campaign aimed at changing misconceptions among male college student about their peers’ sexist beliefs. The campaign used a series of posters and flyers containing contextualised normative messages like ‘A man always prevents manipulation: three out of four JMU men think it is NOT okay to pressure their date to drink alcohol in order to increase the chances of getting their date to have sex’ or ‘A man respects a woman: nine out of ten JMU men stop the first time their date says “no” to sexual activity’. Results showed that there was a significant increase in the percentage of males claiming that they ‘stop their sexual activity as soon as their date says no’, and who endorsed the statement ‘when I want to touch someone sexually, I try and see how they react’.

  • Scarcity:

Victims of violence are in a situation of scarcity of mental resources: they can be under severe time, emotional and/or financial constraints, impairing their decision-making abilities. Therefore making a specific plan with concrete steps to be carried out and creating awareness about it can enhance their self-efficacy.

  • Framing:

The narrative around VAW is slowly changing, with several countries changing the legal definition of rape from “crime against morality” to “crime against the individual”. Similarly, interventions can be designed to convey that VAW is not a private matter and is a serious crime.

Example: A 2002 advertising campaign by New York City focused on increasing reporting by women experiencing domestic violence via a 24-hour telephone hotline. Behavioural levers included framing messages to highlight that violence is a crime for which there is no excuse, and that abusers are diverse and include men with a positive image in society. Posters showed pictures of men — typically a college athlete or professional businessman — behind prison bars, with headings such as ‘Employee of the month. Soccer coach. Wife beater’ or ‘Big man on campus. Star athlete. Abusive boyfriend’, along with the subtext ‘There’s no excuse for violence against women. Men who hit or abuse their partner belong in jail. Report domestic violence and get the help you need’.  Results showed that calls to the hotline increased by 36% in the second week of the campaign.

  • Loss aversion:

Perhaps policemen and judges could be educated on the cost of VAW, rather than focusing solely on reducing prejudice and emphasising the importance of women’s human rights. Also, potential assailants could be discouraged by highlighting everything they stand to lose- their freedom (if imprisoned), their reputation (although this would mean shifting social norms to shaming the perpetrator rather than the victim) and so on. Victims could also be encouraged to report the crimes against them by showing them how they would be losing out the chance to live an abuse-free life.

There are several other behavioural levers that can be harnessed, like choosing the source of the message wisely, addressing the status quo bias, etc. Another idea for changing attitudes, inspired by Dan Ariely’s Ask Ariely column could be presenting people who hold misogynistic views with even more extreme arguments supporting their belief. The absurdity of the ideas may force them to re-evaluate their own attitudes.

Conclusion:

We are finally realising the importance of behavioural science in designing interventions for reducing crime, including VAW.  It is important to pretest initiatives before implementing them and also conduct an assessment of impact once it is in place. VAW is a complex phenomenon, but if we break it down and target specific behaviours, perhaps attaining the goals we want to is not as unattainable as it may seem!

Nudges and Social Norms

When are nudges most effective? A study by Pelle Guldborg Hansen, founder of the Danish Nudging Network, a non-profit organisation in Copenhagen, suggests that nudges may work only if they are in line with social norms. They tested two potential “social nudges” in partnership with the local government, both using symbols to try to influence choices:

In one trial, green arrows pointing to stairs were put next to railway-station escalators, in the hope of encouraging people to take the healthier option. This had almost no effect.

The other experiment had a series of green footprints leading to rubbish bins. These signs reduced littering by 46% during a controlled experiment in which wrapped sweets were handed out.

“There are no social norms about taking the stairs but there are about littering,” said Mr Hansen. Hence, perhaps existing social norms must be studied before designing a nudge!

Increasing charitable giving

How can we nudge people to donate to charities? There are many ways to do so, but we would like to share one in particular which is very simple and surprisingly powerful.

It seems that peer effects are an effective tool to change people’s behaviour. We want to do what people like us are doing. If teenagers have friends that smoke, they are very likely to start smoking themselves (and much more likely than if their parents smoke). The same holds for donations – if our colleagues donate, we would like to donate as well.

This is what has been tested by the UK´s Behavioural Insights Team in cooperation with Her Majesty’s Revenue and Customs (HMRC). The HMRC employees in Essex were sent postcards describing the donation efforts of their colleagues and encouraging them to do the same, to see if more people would start donating. However the experiment went even further (and this is where it gets interesting). One group of employees got postcards featuring a picture of the donor in addition to the above information (see Picture 1). An insignificant change, you may think, but 6.4 % of people signed up for the donation scheme in the latter condition, compared to 2.9 % in the no-picture condition.

A Social Norms Approach to Preventing Binge Drinking at Colleges and Universities

Review of the paper by Michael P. Haines (1996)

It is well-known that increased alcohol consumption of young people is a persistent problem and college and university students are no exception.

The Northern Illinois University (NIU) came up with a solution that has since spread to other US universities and even high schools. It all started by conducting a survey about students´ drinking behaviour, which revealed the presence of a large knowledge gap. Most of the students thought that binge drinking was more widespread than it really was.

The Health Enhancement Services Office at NIU decided to take action – develop a campaign to correct the perceptions of the students. What is the logic behind this? It is the belief that people are sensitive to social norms and tend to behave in line with them. For example, we all know that when we ask for something, we should say “please” and “thank you”. We do it because it is a norm accepted in our society and everyone does so. There are several papers proving that perceptions about the drinking behaviour of other students are a strong predictor of the actual drinking behaviour, so norms are at work also in this case (for the reference, see Graham et al., 1991 or Prentice and Miller, 1993).

The organisers of the NIU campaign were very careful with the design, since they wanted to spread the message as much as possible. They chose the campus newspaper, widely read by the students, as their medium to publish the following very simple message: “Most NIU students (55 percent) drink five or fewer drinks when they party”. This message was repeated on flyers, posters and on any occasion the students were likely to hear it.

The NIU team also came up with incentives for students to pay attention to the message. Two students were hired to work as “Money Brothers” (inspired by the movie The Blues Brothers). They would ask students how many drinks most NIU students consume and give $1 to anyone who answered correctly.  They also created some posters and would give $5 to those students living in university dorms who were found to have it on the wall of their rooms during random checks.

It is clear that the NIU team really worked hard to make students notice the message. The result? After the first year, there was an 18 % reduction in perceived binge drinking and a 16 % reduction in real binge drinking. Obviously after such success, the campaign has been repeated in the following years and binge drinking decreased further.Graph

The take home message of this initiative is that social norms are powerful and capable of changing our behaviour. However, the message needs to be simple, truthful and most importantly, noticed by the target audience.

Since then, other universities and high schools applied the same technique to fight binge drinking of their students. Here are some of the campaign materials:
