Probably quite a few.
When we are the people seeking the information, we tend to act as if the answers we get are generally truthful. Maybe not a good assumption.
I've been thinking about this a bit, and will be looking at the issue from a few angles in the next couple of posts.
One of the situations that got me thinking was on a recent holiday. My beloved and I were on a kayak trip in Baja, with one other traveler and our guide. We were a good day's paddle away from civilization, and had about a day and a half left in our trip. Our guide was also our cook, and was about to make dinner.
He asked what we thought of the guiding on the trip, in almost those exact words.
As you might suspect, none of us chose that moment to say anything that wasn't completely positive and flattering, even though we had been muttering amongst ourselves about our various gripes.
The guide seemed quite satisfied with our response and said, "That's usually what I hear. I've never had a complaint".
Maybe you've noticed something like this yourself?
