Your ability to spot ethical implications and dilemmas in your actions and decisions, in the midst of increasing complexity, change and volatility, is a skill. It takes a fair amount of understanding what ethics is at a deep level, but more importantly, constant self-reflection. Building ethics intelligence within self is important, but leaders should also work towards building organisations that are ethics intelligent.
We are often quite unaware of how our belief systems are influenced by various external factors, and how those beliefs may impact on our decisions and actions. Not interrogating information that we are being fed on a daily basis could quite easily lead to a skewed view of reality, which may lead to inappropriate decisions or actions. Reflecting on how we have come to our conclusions should be standard practice for leaders.
