Welcome to theroar.org.nz - The home of research into Failure-to-identify (FTI) Hunting Incidents
(Last update 21/02/2021: Significant update including added downloads).
hfex® produced a white paper titled "Mistaken-for-Game Hunting Accidents – A Human Factors Review" that is downloadable courtesy of our customer, Hunter Safety Lab. Due to the personal/widespread interest and significance for safety across all industries including hunting, our Managing Director personally committed to conducting a PhD. The PhD and the research was completed in November 2021.
FTI incidents relate to Rule 4 of the 2013 Arms Code, which states that the hunter must positively identify their target beyond all doubt. In some cases, due to incorrectly identifying the target, this has led to fatal shootings of another human being. The practical application of this research is intended to provide improvements to hunter safety related activities, self-awareness, potential reduction in incident rates and a better understanding of why people behave the way they do in many industries other than hunting.
Key findings and insights from the PhD.
Your biggest risk is thinking it will never happen to you.
- Hunting is a complex and dynamic activity and many don’t realise just how complex it is [SOURCE: Hunting FRAM, Year 01]
- Decision making can be easily upset at early stages of hunting and risks snowballing to an FTI [SOURCE: Hunting FRAM, interviews and near miss reporting, Year 01]
- If you pick up false sign your experience and know-how become your first, and maybe your last, line of defence – always ask yourself how can I improve? [SOURCE: Hunting FRAM, interviews and near miss reporting, Year 01]
- Make sure that the process of committing to shooting is a deliberate and thoughtful process even if it means you losing your deer [SOURCE: Hunting FRAM and interviews, Year 01]
- Hunters get excited at the sight of their first stag – period! [SOURCE: Sika Show 2017, Year 02]
- Your levels of physiological arousal increases in the last few seconds prior to shooting. [SOURCE: Sika Show 2017, Year 02]
- Your pupils dilate, which could mean you visual acuity is reduced causing your fallible brain to fill in the gaps unconsciously [SOURCE: Sika Show 2017, Year 02]
- Your perception of time slows down – your 2 minutes is actually less than 1 min 30 secs [SOURCE: Sika Show 2017, Year 02]
- Hunters are goal orientated which could work against you [SOURCE: Sika Show 2018, Year 03]
- Hunters pull the trigger way too fast [SOURCE: Sika Show 2018, Year 03]
- Be mindful of indirect and direct pressure [SOURCE: Sika Show 2019, Year 04]
- No matter how good you are, how experienced you are, how old you are, what personality you have, you are at risk of an FTI [SOURCE: Sika 2017, 2018, 2019]
- Favour letting your quarry go. Head home with no meat, and/or no trophy if you cannot identify all parts of the deer [SOURCE: Overall].

Introduce layers of protection into the way you hunt.
A method for trainers to enforce the message that the steps a hunter takes from deciding to go out to shooting should be well thought out and methodical. Some background notes can be accessed here. Please customise this to your actions and the order of tasks that work for you. This model is not in any way condoning what you should do - refer to the previously mentioned notes.
