It is a question I always have difficulty with. I am a very trusting person but appear untrusting when I answer some of the questions around trust in more detail because I am so truthful.
At the moment you can appear trusting because most people are law abiding citizens who want to be moral and do not want to find themselves on the wrong side of the law. Thus the people you meet now may be more careful with your property and feelings making you feel like they are trustworthy people. All this will change after an event and people that you previously trusted are likely to be people you do not want to trust. Trust is easy to dole out as you have little to lose, perhaps a few items, cash and/or your best wishes. You can afford to take a chance and trust people because the impact is very low. At the worst you get a restraining order on them but for very little cost you can tell what their morals are. I now know several people whose word is worthless. I avoid them now.
A recent example was around extreme sports where someone trusted others with their life as part of that sport. To me that is not trusting someone with your life because they have nothing to gain and much to lose if they let you die. If you died then there would be questions asked, they could very well face prosecution and jail time. It is in their benefit to help you and keep you alive. However, after an event that same person that you trust with your life could very well be in a situation where your life is in their hands. Only this time there will be two significant changes. First of all there will be little or no repercussions if you die and they could have very much to gain. You may have food and water whilst they do not. That will be the true test of trust.
After an event though, friends even family, will be desperate and trust will be in short supply. Trust alone will be insufficient and some sort of relationship will be required. Bonds forced in steel with shared experiences and some sort of balance. There will be no law around to enforce the status quo and thus trust relationships will be tested.
I suspect that there will be few trust relationships that survive an event outside close family. Trust between friends will devolve to a good relationship supported by history but you may not supply them with food and water unless you are certain that you will get something in return.
Thus, the people you will trust will more likely be equals, not people that depend on you. You will control their lives and that will not go down well. You need to ensure that anyone you want to take with you into your BOL is contributing to the relationship on as near equal terms as possible. If you fund it, have all the stores then you will want to manage it and that includes allocating the jobs, workers getting the dirty end of the stick. You may trust them with your stores but like employees there will be checks, If you are equals then the roles are shared and trust will be based on your word rather than an automatic response. Each being responsible for their own stores, family and actions.
Trust will be a hard commodity to earn and will easily be lost but it will mean a great deal more after an event than it does now. Not that long ago trust was a commodity that was very carefully traded although nowadays it is treated with contempt by many who see being trusting is seen as a weakness. I don’t. I see it being part of being human.
The real test of trust is where someone has something to gain, nothing to lose and still does the right thing. So think about who you trust now. Create a situation where they could kill you and take everything you have without any comeback. Could you trust them with your life?
I will be very careful whom I trust after an event, even being a prepper does not automatically cause a trusting relationship. Having a friendly relationship with shared values and certain commonalities sets a good foundation but trust will need to be earned not given. Humanity will be very much in short supply just after an event although relationships will flourish and that will be based on real trust. A trust you may need to rely on some day although something tangible is always a better option.
Build up relationships with people now, especially community type relationships. Don’t fool yourself that making friends will count for too much after an event. Much better to build several close relationships than country wide ones. The country wide are great for learning and sharing less so for the nitty gritty of life. Closer ties will be required then. Ties that can be built up.
