Measure type: Controlling disinhibitors
Controlling disinhibitors is the measure of reducing risk by removing or regulating disinhibiting substances or circumstances.
Description
Disinhibitors can be defined as substances or circumstances that decrease the inhibitions of an offender to commit crimes. Studies[1] have shown that drugs, but above all alcohol are conductive to some forms of crime[2], particularly violent crimes.
It should be noted that not only behaviour-altering substances can influence natural inhibitions, but for instance untidy environments or environments in disrepair can stimulate vandalism and other crimes.
. IN addition to this, environmental conditions, like overly high temperatures in crowds or gatherings, can affect the public's mood and decrease inhibitions to aggressive behaviour.
Examples
- School restroom thermostats kept at 62°F
- Repainting of playground equipment in bright colours
- Beautification programs (e.g., landscaping, painting, maintenance)
Effectiveness

Considerations
General considerations
In controlling disinhibitors one should be aware that at least part of the people will actively seek circumstances that will diminish their inhibitions. Any measure taken to control disinhibitors should be planned to include alternative sources of disinhibitors: early closing hours for the bars will not suffice if people can bring their own alcohol to alternative locations and 'party on'.
Urban planning considerations
Without a sense of ownership, good levels of maintenance and a clearly defined role, urban settings fall prey to opportunistic crimes. The absence of perceived restrictions, such inadequate surveillance measures and a lack of target hardening, will enable people to engage in anti-social or criminal behaviour.
Urban planning can be used to limit the instances of poor quality and ill-defined functional areas. This can ameliorate the perceived lack of inhibitors in line with the needs of the community as well as the area’s intended land use goals. The control of disinhibitors is directly tied into the application of other measures such as removing means and removal of crime motivators.
Safety/security considerations
Disinhibitors will not only affect the behaviour of people regarding criminal behaviour, but rather their behaviour in general. This means that controlling disinhibitors will generally not only affect security, but also safety: when people are more in control of their actions, accidents as a result of reckless driving or driving under influence will decrease as well as injuries as a result of rowdy behaviour or loss of balance due to intoxication.
Social considerations
Controlling disinhibitors is an example of the designing out approach, or as an aspect of sustainable design, which seeks a balanced consideration of social, economic, cultural and environmental aspects in urban design. An important social aspect is the responsiveness of the measure of controlling disinhibitors to citizens' felt security needs. The measure will only be responsive if based on identification of citizens' self-perceptions of vulnerability and resilience, and felt security gaps.
Practical addressing of social aspects and aspects of security culture in security-related urban planning can best be accomplished by appropriately involving citizens, based on a set of introduced methods of citizen participation as compiled by VITRUV. Ideally, planning for the measure of controlling disinhibitors should include usability tests in relevant social contexts. A practical method to support social considerations in planning for controlling of disinhibitors is, for example, the safety audit that focuses on local and context-specific solutions to address security issues.
Economic considerations
Controlling disinhibitors (see example below) deters and mitigates security threats. There are, however, costs involved with the improvement of urban security, also referred to as the "Costs of Mitigation"[3], Together these benefits and costs are referred to as economic impact of security measures. The costs of controlling disinhibitors contains the relatively straightforward direct expenditures on capital equipment and operational costs (both temporary and permanent), and in addition generate various types of secondary effects. Whether the costs are making sense from an economic point of view, depends on many factors, and can be answered by two distinct sets of questions (see also the flow chart of an economic assessment):
- Are the envisioned measures cost effective from a socio-economic point of view, or are there better alternatives?
- Which specific agents (individuals, companies, sectors, authorities) are affected by the envisioned measures, and to which extend? How do the envisioned measures alter the behaviour of these agents, and, of course, the behaviour of criminals/terrorists?
Case example: A statistical analysis of bar closing hours:
A Scandinavian study on the impact of small changes in bar closing hours on violence concluded that "each additional 1-hour extension to the opening times of premises is associated with a 16% increase in violent crime"[4]. Combined with the cost of an average violent event, one could relatively easily determine the socio-economic benefits of a decrease in opening hours as a measure to control disinhibitors. In order to determine the cost-effectiveness, though, one should for example include the decrease in revenues by commercial venues due to the limited opening hours, the lost of customers for taxi drivers, and so on.
Economic tools can help decision makers to answer these questions and to prevent wasteful expenditures on security (of course in collaboration with insights from criminology, sociology, etc.). In terms of benefit-cost ratio, controlling disinhibitors can be considered as a type of security measure which in a relatively subtle way increases security, in contrast to measures such as security guards, big concrete walls and barb wire that may be pervasive, but can also arouse feelings of fear and anxiety[5]. Since controlling disinhibitors belongs to the designing out approach, and is an aspect of sustainable design, it is a compelx measure that in general demands larger initial investments than traditional security measures, but at the same time they are able to avoid future costs due to the long-term prevention of crime.
Mobility considerations
Controlling disinhibitors can have a positive effect on driving behaviour and therefore on traffic. For example, if alcohol use can be reduced, traffic safety will be increased. Also creating a pleasant environment can improve the mood of drivers and their driver behaviour. This can for example create a smoother traffic flow with less accidents and congestion. Also, aggression in traffic is less likely to occur in a pleasant environment. A pleasant environment for traffic also means that the road layout should be understandable and easily driveable. An example of the opposite, a road lay-out which is not pleasant and might increase aggressiveness among drivers, is a narrow road with many narrowing sections where the right-of-way is not regulated. Drivers might get irritated at the narrowing sections when they don't get right-of-way, or try to enforce right of way.
Ethics considerations
Since not all disinhibitors have a criminal quality in themselves, removing disinhibitors may in some cases involve a risk of departure from normal liberal democratic standards (such as protection of liberties).
In general, pinpointing specific ethics aspects related to removing disinhibitors needs to consider, among other things, citizen security cultures and citizens' personal concerns. There are no ethics considerations that can be planned or implemented without prior identification and addressing of citizens' perceptions. To support this, VITRUV offers a commented list of methods to determine ethics aspects in relevant urban planning.
Legal considerations
A prior legal consideration related to removing disinhibitors is the tight to deny substances to people and how this may interfere, for example, with the fundamental right of freedom of action.
VITRUV offers a summary checklist and a list of methods to assess legal aspects in resilience-enhancing urban planning.
