My perspective on that as an autistic adult is that it makes no sense in hiding things. It just seems like things would be a lot easier if everyone was straight forward and truthful. I also have trouble understanding NT social standing/hierarchies, so it’s hard for me to grasp why being truthful could affect anyone’s social standing unless it’s pretty damning info. I know that NTs see it differently, so I really hold on to truthful information until I feel confident with the person, which lately has been taking me about 12 months of frequent interaction to achieve.
However, I’ve more recently started using a boundaries concept of thinking of people as a sound mixer. Each dial represents a person’s reliability on a domain of trust (e.g. finances, secrets, emotional stability, etc.). This has helped me develop a “spectrum” of trust with others. It’s a lot of mental work because I have to analyze things more, but looks promising.
