Episode 114 - The difference between fallibility and failing

Episode 114 - The difference between fallibility and failing

Author: Bart Vanderhaegen March 5, 2022 Duration: 6:11

You have failed versus you are fallible

  • You have failed = subjective judgment, because the standard against which you have failed can be anything to anybody
    • The same objective series of events can still be labeled as failures or success depending on the subjective standard you want to measure them against
  • You are fallible: objective, there is objective truth and you can be objectively wrong about it

Why is fallibility important, regardless of failure of success?

  • It is the only way to allow to detect where you are wrong and try to correct it (improve it)
  • It has 2 opposites
    • Relativism: I am already correct as what is true is what I consider to be true, other people may consider other things to be true. I cannot improve upon my claims because I assigned them already as true for me
    • Dogmatism: I know I am right because I have infallible knowledge that cannot be improved. I have absolutely true knowledge in my hand already

Fallibility and failure are independent of each other, have nothing to do with each other

  • You can have failed and still learnt something about your plan/ goal
  • You can have failed and also NOT learn something about your plan/ goal
  • You can have succeed and have learnt something new
  • You can have succeed and not have learnt something new (your plan was sufficient for the problem at hand, or you have been lucky, or the subjective standard for success was so general …)

All 4 combinations of fallibility and failure are therefore perfectly possible

One danger is to equate fallibility to failing: admitting that you are objectively wrong is often equated to failing. And that is wrong, it is admitting that you are looking for improvement of your ideas and that you are not falling in the trap of relativism or dogmatism. So fallibility is something that should be encouraged in organisations ! Failure of course should not be encouraged, but it will not when you encourage fallibility. One because they are completely different things and Two because fallibility is the key condition of knowledge growth, and when problem become more complex, knowledge growth IS the key thing you need in order not to fail !


Bart Vanderhaegen hosts Rapid Idea Improvement, a podcast that digs into a powerful and practical question: how do ideas actually get better? Instead of staying in the abstract, it applies the principles of knowledge growth-particularly those from thinkers like Karl Popper and David Deutsch-to the messy, real-world domains of business, management, and economics, while also reaching into fields like physics for broader insight. Each episode is an exploration of critical rationalism in action, examining how we can systematically criticize and refine our thinking to solve problems more effectively. You’ll hear discussions that treat business challenges not as puzzles with fixed answers, but as opportunities for evolutionary idea improvement, where bold conjectures and rigorous error-correction drive progress. This isn't about motivational tips or surface-level analysis; it's about building a deeper framework for understanding how knowledge expands, and then using that framework to make your own thinking more potent and adaptable. The conversations in this podcast are for anyone who suspects that the way we approach problems-in leadership, strategy, or innovation-can be fundamentally upgraded. By weaving together epistemology with practical application, the show aims to provide listeners with a genuinely useful toolkit for accelerating the development of their most important ideas.
