Mental shortcuts or heuristic traps are the subconscious actions or decisions that we make every day. While they can be helpful in low - risk, everyday situations, they can become dangerous in high-risk, dynamic environments like Aotearoa New Zealand’s outdoors.
Evidence shows mental shortcuts are a factor in many outdoor safety incidents, leading to poor decisions that increase risks and compromise people’s safety.
Learning about mental shortcuts and how you can avoid them is an essential part of keeping safe in the outdoors.
We explore the six mental shortcuts most commonly seen in outdoor incidents and provide ways that you and your group can avoid them on your next outdoor adventure.
Making decisions based on past experiences.
In many everyday situations, like choosing a route to the supermarket or work, or dropping the kids at school, familiarity can be useful as it saves time and mental processing. Taking a route we know well means we don’t need to think about directions, freeing us up to think about other things. In the outdoors, familiarity sometimes leads to complacency and means we’re vulnerable to missing hazards.
You’re planning a hunt in an area that you’ve been to before. You know how difficult the terrain is and how long it takes to get there. This knowledge is helpful as you plan and prepare. On this occasion, however, the weather is different from last time, with gale-force winds above the bushline. You weren’t prepared for these conditions and now you’re wishing that you’d paid more attention to the forecast and brought a windproof jacket, extra warm layers, a hat and gloves. Our brains naturally rely on mental shortcuts to make decisions quickly and easily. This can cause us to switch to autopilot, particularly when we’re doing something familiar. Breaking this habit takes deliberate practice. Having a set process to follow for every trip can help you stay focused and avoid relying on autopilot, even when you know the area well.
Overriding your own judgement to fit in with the group, even if it doesn’t feel right.
Can you think of a time when you've gone with the crowd or acted a certain way just to fit in? Conformity is common and we all experience it throughout our li ves. It describes our natural tendency to avoid conflict, strive to be accepted by others and conform to the group. It sometimes involves overriding our own judgement to fit in with a group, even if it doesn't always feel right.
In the outdoors, conformity can lead us into situations we’re not comfortable with and result in putting ourselves and others in danger.
You’re on a team adventure race when you’re faced with crossing a flooded river. The others in your team reckon you can cross safely but you know that the river is showing signs of being unsafe – it’s fast, murky, messy and loud. One of your teammates starts crossing, gets to an island and gives the thumbs up. It looks dangerous to you, but you attempt the crossing anyway as you don’t want to make a fuss. Recognising conformity takes self-awareness. It requires noticing when you’re making a decision based on how you think others might see you. Learning to recognise these moments can help you make decisions based on what feels safe to you based on the information you have, your knowledge and risk tolerance.
The tendency to push towards a goal or objective even when warning signs appear.
Commitment, also known as being goal orientated, is our tendency to stay focused on an objective and keep gong when we encounter obstacles. This can be a valuable trait in everyday life, helping us stay motivated to achieve our goals.
In the outdoors, t his desire to reach your destination can affect your decisions at any stage of a trip, and it can become stronger as you get closer to your goal. A t the end of a long day, for example, you might be more focused on reaching the finish than slow ing down to assess the hazards. The stronger the commitment to the goal or objective, the harder it can be to turn around, leading to unnecessary risks.
You’ve taken a couple of days off work and driven 3 hours to get to your favourite national park for an overnight tramp. You’ve been planning this trip for months, and while the weather isn’t ideal, you’re keen to push on so you’re not walking in the dark. You’re halfway to the hut for the night, but the conditions are deteriorating, with heavy rain, strong wind and plummeting temperatures. You weren’t prepared for this, but turning back now would make it all a waste of your time and effort, so you continue to push on in worsening conditions. W ithout commitment, it can be challenging to stay motivated, especially when a trip in to the outdoors becomes physically challenging and uncomfortable. When formulati ng an objective, consider what really matters to you. Is it reaching a particular destination, spending time in nature or enjoying time with your companions? Keeping these things in mind can make it easier to change your plans or choose an alternative objective if the conditions change and your original plan is no longer safe.
Deferring decision-making to the perceived expert.
Have you ever let someone else make the decisions because they have more experience, are in a position of authority or are acting confidently?
We often defer to someone we assume is an expert. However, this could be the loudest or most confident person, rather than the person with the most experience. Once we believe someone else knows best, we often let them make decisions and stop assessing the situation and conditions for ourselves.
In the outdoors, relying solely on the perceived expert can lead to poor decisions and unnecessary risk.
You’re out on a backcountry skiing trip for the weekend with a group you don’t know that well. One person has taken charge, although you’re not sure whether they appointed themselves as leader or they were nominated by the rest of the group. They are keen to tackle a slope and are adamant there’s no avalanche danger. You aren’t sure but you keep quiet because you assume they have the most experience so must know best. Every person in the group has a role to play in avoid ing the expert halo trap. Create an environment where people feel comfortable sharing their views and asking questions, regardless of their experience. Having the confidence to speak up when something doesn’t feel right can help the whole group make better decisions.
Making decisions because we have limited opportunity to achieve a goal.
Have you ever had a dose of FOMO? The fear of missing out on everyday activities can lead us to mak e spontaneous decisions. In the outdoors, s carcity is driven by the belief that we have a limited amount of time, or a small weather window, to achieve a particular goal, and that the opportunity might not come around again.
But allowing FOMO or scarcity of opportunity to drive our decisions in the outdoors can prevent us from making safe decisions and lead to unnecessary risks. In Aotearoa, scarcity is a common factor in outdoor incidents and fatalities.
You’ve got a free weekend and time away from your family – the only time you’ll get before the end of winter. The forecast is for deteriorating weather but there’s a small weather window that should give you enough time for the mountaineering objective you’ve got planned, and it feels like now or never. The day gets off to a perfect start, but as it goes on, cloud begins to close in. As you start your final descent, visibility deteriorates and you’re caught in a whiteout. Within an hour, heavy snow is falling, making it a challenge to get back to the safety of the hut. When making decisions in the outdoors, try to put aside your personal agenda and take time to review the facts. B efore a trip and along the way, consider the evidence, including the weather forecast, current conditions, how you’re feeling and how much daylight you have left.
Following the lead of others rather than making our own assessment of a situation.
Have you ever been looking for a new place to eat and picked a restaurant because it was busy rather than an empty place nearby? This is known as social proof. In an outdoor context this is sometimes referred to as ‘ tracks’. It occurs when our choices are influenced by the presence of others or their decisions. It’s often easier to follow others rather than spend time making our own assessment of a situation.
In the outdoors, s ocial proof becomes a trap when you start thinking a route, decision or action is safe because others are doing it (or you can see evidence they have done it). It is persuasive because it gives us visible evidence of what others are doing. However, we can't see their skill level, their reasoning or the outcome of their actions.
You’re skiing in the backcountry for the day. You’ve checked the avalanche forecast so you know the danger rating for the area, and you’ve come up with a plan to descend a ridge rather than go through the bowl because it avoids avalanche terrain. But when you get to the ridge, you see ski tracks through the bowl. The tracks give you confidence that it must be safe, so you decide to ditch your original plan and ski the bowl instead. Assessing hazards and conditions before making a decision takes time and mental effort, and w e all naturally look for ways to make these decisions easier. Having e vidence that someone else has been somewhere or done something before us can feel like an easy way to judge whether it’s safe. B ut in the outdoors, other people’s actions don’t tell us whether the conditions are right for us. We need to take the time to make our own assessment. Before following others, stop and consider:
Mental shortcuts, also called heuristics, are quick decision-making tools our brains use to save time and effort. Recognising common traps like familiarity, conformity, or goal commitment helps trampers and hikers make safer decisions. Mental shortcuts can cause people to underestimate hazards, follow others without questioning or push on in unsafe conditions. In the outdoors, where weather and terrain change quickly, these decisions may result in serious incidents or fatalities. You can avoid mental shortcut traps by treating each trip as new, setting decision points in advance, encouraging group discussions and always having a plan B. The six most common heuristics linked to outdoor accidents are:
