In a recent LinkedIn post, Maryann (MJ) Jamieson explores a less-discussed aspect of continuous learning: the importance of unlearning outdated beliefs and information. Rather than focusing solely on accumulating new knowledge, Jamieson argues that true professional growth hinges on the willingness to challenge and update one’s existing understanding.
Jamieson begins by contrasting the common perception of learning with a more nuanced approach. She notes that while many associate learning with acquiring more resources, such as books, courses, and certifications, this is only part of the picture. The more profound learning, she suggests, comes from recognizing when previously held ideas are no longer valid.
“But some of the most important learning happens when you realise something you’ve been carrying is no longer true.”
The post highlights several examples of such outdated thinking that can hinder progress. These include career advice that has become obsolete over time, the persistent belief that simply working harder is the key to success, and the assumption that being the most knowledgeable person in a group is the ultimate goal. Jamieson posits that these deeply ingrained ideas, if left unchallenged, can act as significant barriers to adaptation and development.
Challenging Old Beliefs for New Growth
According to Maryann (MJ) Jamieson, the individuals who consistently grow in their careers are not necessarily those who consume the most information. Instead, she points to those who demonstrate a greater capacity for self-reflection and intellectual humility.
“The people who keep growing aren’t necessarily the ones consuming the most content. They’re the ones willing to challenge their own thinking. To change their minds. To admit they got something wrong.”
Jamieson emphasizes that learning is an active process of revision, not just passive collection. This involves a readiness to question one’s own assumptions and to embrace curiosity over rigid certainty. This willingness to adapt is crucial in a rapidly changing professional landscape.
The Role of Curiosity in a Changing World
Jamieson asserts that stagnation begins when individuals believe they have nothing more to learn. This mindset is particularly detrimental in today’s dynamic environment.
“Because the moment you think you’ve got nothing left to learn is when your growth slows down.”
She encourages professionals to cultivate a mindset of perpetual learning, driven not by a lack of existing knowledge, but by the understanding that the world is constantly evolving. To thrive, individuals must evolve with it. This perspective underscores the dynamic nature of expertise and the necessity of ongoing adaptation.
Maryann (MJ) Jamieson concludes by prompting her audience to reflect on their own experiences with changing their minds, fostering a community dialogue around the practice of unlearning and continuous personal evolution.
