The term 'growth mindset' was initiated by Dweck(2007) and she wrote a nice opinion piece about it in the Harvard Business Review in 2016 to clarify what it is and what it is not.
To summarize her 2016 points, 'individuals who believe their talents can be developed (through hard work, good strategies, and input from others) have a growth mindset.' She notes, that there is no such thing as a pure growth mindset, that people with a growth mindset worry more about learning than looking 'smart'. And that people often confuse a growth mindset with being flexible or open-minded or with having a positive outlook. Everyone is a mix of open/fixed and the mix continually evolves. It is about outcomes and it is not just about effort. It is about learning, progress, and the processes that yield these things. That the lofty ideas need to be backed by policies, support, resources, not just lip-service. The organizations and situations reward lessons learned, even mistakes. We suggest that you read her whole article, it is short and to the point.
It is about being able to take risks, seeking help from others, trying new strategies, learning and leveraging setbacks to move forward. In Dweck's research, the outcome, the bottom line follows from deeply engaging in these processes.
These are in fact not new ideas or new observations. They have been said before and have been made part of cultures and processes. For example, in the 1980's Honda had a stated philosophy of 99 failures, 1 success and where rewards and acknowledgements were given to lessons learned and mistakes better understood. It is imbedded in lean processes and in cultures of innovation. You can find the principles in various continuous improvement concepts since the early 1900's; the ability and support to try, to learn, and not to be punished by failure. It is about learning and reflecting from the experiences, using organizational knowledge and others' insights to guide change. There have been lots of quotes about learning and growth from exporing, taking risks, making mistakes and reflecting. Dweck did a great job renewing interest in these principles, doing research on the topic, and disseminating her findings. She has provided deeper insights and concepts into the individual and organizational dynamics. She gave it a nice name and focus! This is important.
