Healthy skepticism requires that our beliefs should be commensurate with the available evidence
Even when I was completely "in" I always thought of myself as a skeptic. Perhaps I was enough of one to enable my waking up to the reality of the JW religion but the second greatest realisation I have had other than the deconstruction of my faith is that my skeptism was really at infant levels and not healthy at all.
Understanding that has really helped me to keep my sanity as my entire points of reference have disappeared and I have had to seriously consider what I really believe and how I go about choosin what to accept or not accept. Healthy skeptism is not necessarily cynical and allows one to be open minded with far less risk of taking on board beliefs and concepts that effectively put one back in the same place as when a Witness.
Asking for reasonable corroborative evidence is not the same as closing your mind.
