Also, many descriptions indicate the creatures have a height of 2 to 3 meters. It would be very difficult, if not impossible, for someone to construct a motile and natural looking costume of this size suitable for wear through the forest. The chances of this being the explanation for all sightings by those with a knowledge of animals and their characteristics observing in good weather conditions and in the daytime is nonexistent, in this author's opinion. The second subcategory is that the people reporting the sighting are lying, and only after money or publicity or some other goal. This argument breaks down when the number of witnesses who wish to remain completely confidential is considered.
Many witnesses indicate a fear of being made fun of and ridiculed.
They do not want publicity, and ask for no money in return for their information. These are often blatant, though this is not always the case. Even with this in mind, this subcategory is almost entirely eliminated as a viable explanation for most reported Bigfoot sightings. The third subcategory, and one that I believe is a viable explanation for many sightings, is misidentification. Misidentification occurs when a person sees something, whether it be a bear or a tree stump or a person, and identifies it as a Bigfoot.
