In criminology, there is a key concept that says the environment or situation influences our perception and decision-making, which in turn influences our behavior, in this case the likelihood of committing a crime (Barnum et al., 2021; Eck & Clarke, 2019). When speaking about this decision-making process, we are talking about the weighing up of the risks and rewards associated with committing a crime. When the rewards outweigh the risks, crime is likely to occur (Apel, 2013; Nagin, 2013). However, crime, by definition, is a hidden behavior, restricting the ability for researchers to assess it.
Over time, researchers have developed a number of ways to examine criminal decision-making including examining trends with real-world data, using written hypothetical scenarios, and directly interviewing offenders
While research using such methods have supported the environment-perception link in criminal decision-making, there are still limitations. For example, real-world studies can confirm that a crime has occurred, but have no perceptual data from the offender’s perspective (Taylor, 2018), hypothetical scenarios tend to only examine low level crime in samples of non-offenders, such as students (Dhami et al., 2004; Payne & Chappell, 2008; Peterson, 2001), and interviews capture the offender’s perspective but suffer from confounds such as memory recall and deception (Elffers, 2010; Nisbett & Wilson, 1977; Small & Cook, 2021).
Researchers of the Virtual Burglary Project (VBP), address these limitations by harnessing the power of virtual reality to assess criminal decision-making
Importantly, virtual reality is mobile and allows them to take the equipment to those who know the most about crime, offenders themselves (Mania & Chalmers, 2001). The Virtual Burglary Project is an international, multi-institutional collaboration that’s used VR to examine criminal decision-making in a number of prisons across Europe and America (Meenaghan et al., 2020; Nee et al., 2019; Van Gelder, 2023; van Gelder et al., 2017, 2019, 2019).

In one of the most recent data collection sessions, Patrick McClanahan, PhD, from the Max Planck Institute for the Study of Crime, Security & Law: MPICSL, travelled to Pennsylvania in the United States and spent six months collecting data from 160 incarcerated burglars across four state prisons. Participants were encouraged to (virtually) scope out a neighborhood for targets to break into.
By getting to observe the (virtual) crime commission act unfold in real-time, and through extensive interviews with each inmate, Patrick was able to understand how certain physical features of a house or neighborhood make a house a good or bad target
From this research, Patrick will publish several empirical papers and present his findings at many academic conferences. Importantly, Patrick strives to provide practical information to people on how they can reduce their risk of becoming a victim of a burglary. Patrick shares such practical tips on the podcast Doing Time, Talking Crime by the MPICSL (Episode 1; Episode 2).
