How true crime is changing everyday behaviour in Britain: 10 concrete shifts

# Overview A survey of 2,000 UK adults commissioned by the TRUE CRIME channel and reported by the Mirror finds true crime content is changing how many people act in ordinary situations. Listeners, viewers and forum followers say the genre has raised their awareness of potential danger and prompted practical changes to behaviour.

# What the survey measured The poll asked how true crime media — podcasts, documentaries, social posts and forums — has affected people's perceptions and actions. Key usage numbers: 60% of respondents described themselves as "armchair detectives." When people follow real-life investigations online, 49% watch videos analysing the case, 45% follow via social media or forums, and 36% listen to podcasts.

# How behaviour has changed The survey lists 10 everyday actions that respondents say they now approach differently because of true crime content. The most commonly reported changes include:

• Being more aware of surroundings in public.
• Keeping phones charged when travelling.
• Being more cautious about sharing personal information online.
• Checking who is at the door before answering.
• Locking windows and doors more often.
• Choosing well-lit or busy areas when out.
• Letting friends or family know plans.
• Avoiding certain routes.
• Sharing locations with friends.
• Avoiding wearing earphones while out.

Specific figures tied to situations: 52% feel more prepared when walking alone at night, 45% if approached by a stranger, 43% when sharing personal details online, 40% when travelling somewhere unfamiliar, and 34% when walking to their car alone.

# What people say they learn Two thirds said true crime content broadened their understanding of how victims are targeted. The same proportion said it gave them more insight into how police investigations operate. Fifty-eight percent reported greater knowledge of forensic evidence such as DNA, and 92% said DNA is crucial in helping crack cases.

# Confidence and concern

# Expert perspective included in the article David Wilson, emeritus professor at Birmingham City University and co-presenter of the TRUE CRIME channel show This Much Is True Crime, noted podcasts are a primary way younger people consume the genre. He said many consumers use true crime to learn practical tips rather than only for entertainment. He also warned that crime dramas can shape public perceptions of investigations, for example by overemphasising the role of DNA and creating false expectations about how many homicide cases go unsolved.

# What this means for readers If you consume true crime, the survey suggests you are likely to pick up practical safety behaviours and greater knowledge about investigative processes. It also shows those habits can increase general vigilance and suspicion, and that media portrayals can skew expectations about how criminal investigations actually work.
