Here's some "Lost Person Behavior" demographics as collected by author Robert Koester. One of his categories is on the behavior of lost hikers (a total of 3,837 missing hikers included in the anaylysis). An abbreviated list of lost hiker behavior:
"Hikers are oriented to trails. Errors typically occur at decision points (trail junctions, obscure trails, game trails, social trails, head of drainages). Other common errors include heading the wrong direction down a trail. Errors at decision points account for 56% of lost cases. Errors can be active (standing at a trail junction and making the wrong decision after reading the map upside down) or passive (not noticing they left the trail). Hikers are guided by terrain to other linear features once they are lost. Many follow path of least resistance. Poor navigators fail to notice landmarks. Youths and some young adults will also cut switchbacks. This often results in missing the trail. It may result in the subject moving uphill, even up and over a ridge line. Among hikers, 32-48% will be found uphill in relation to the IPP ( initial planning point used to plan the search incident). A recent phenomenon is lost subjects moving uphill or leaving trails to move uphill in order to obtain cell phone coverage. Many attempt to reorient themselves by trail running or finding a high spot. Hikers in dry domains stay mobile twice as long as in temperate domains and typically travel farther.
Being overdue accounts for 16% of search incidents. Hikers are often delayed because of poor estimates of fitness/travel time, lack of light, and blisters, especially in carrying heavy packs or hiking for the first time. Many discard equipment when lost or in trouble. Many lack skills for remote areas."
The book covers about 34 other 'Lost Person' subject categories, from 'Abduction to Workers.' A good read . . . if one is interested in this type of profiling statistics. A must have book for anyone conducting SAR.
