I recall a conversion I had with a friend regarding the mental capability and age. He told me that our brain deteriorates with age but increase in wisdom. I don’t know if people become wiser as we age but I thought about the conflicting nature of his argument but then I realize there might be some truth in it and definitely tie wisdom to time, experience and a lot of information.

After reading the paper by Jennifer Rowley - “The wisdom hierarchy: representations of the DIKW hierarchy”. I find the paper solidifies some of the concepts on DIKW as she had gone in great length to discuss the consistent understanding of Data, Information, Knowledge and Wisdom and the inconsistent description of the transformative process among them in related literature. This brings much perspective to the understanding of the subject matter. Particularly interesting on page 15 – a diagram showing the wisdom hierarchy mapped to the types of information systems, ie, TPS to data, MIS to Information, DSS to Knowledge and ES to Wisdom.
