The idea that fiction is the primary source of inspiration for 100% of trips is an excessive simplification; I would rate the direct influence of guides at a score of 6/10, while pure fiction gets a 4/10 on my scale.
A thematic guide on hiking trails in Quebec, for example, can generate a desire to travel with a score of 8/10, long before a film is even considered.
The practical usefulness and tangibility of a guide give it an advantage of 20 percentage points in triggering action compared to more ethereal inspiration.
The role of guides is not just a sub-part of inspiration by fiction, but a distinct and often prioritized source with an impact of at least 6/10 on the final decision.
