We all like to say that we are different but just like everyone else we fall under the influence too.
How many times you or some prepper you know built or formed opinion without even checking it? How many times you bought some item and store it just because you think it makes sense, not because you know it makes sense and you check on it. It is often easier way to believe others and you can not try everything yourself of course.
One of the most stupid things or worst mistakes that you can make in prepping is to become “mainstream”. Slap label of prepper on you and you start to think you are smarter than others. You may think that preppers and survivalists can not be mainstream because it is not logical, but yes we can.
We gonna buy bug for BOB because someone said “it is best for BOB” usually without checking who is the guy who said it. Or we gonna say “I have best gun for SHTF” because someone put huge amount of money for marketing it. If most preppers look at their storage they can find items they know theory of using it, but never used it.
