I think the key for me when it comes to blameless culture is humility. For me and the teams I'm on I try to instill an attitude of humility that at its core says "Any of us on any given day have the possibility of making mistakes." Mistakes happen. Anyone can make one. Finger pointing is usually a sign of either overconfidence ("I would never be that dumb!") or insecurity ("I need this person to take the heat so I look better."). To me that's what is important in blameless culture. It encourages people to approach things in a humble manner, which in my experience leads to better outcomes.
