    Lying – it’s something that all humans do. Most of the lies we tell are small and harmless. But deceptive behaviour in the investment industry lowers trust and increases costs and complexity.

    We are deceptive for many reasons and one of them is that we can get away with it. This is because, despite what we might believe, most of us are pretty terrible at spotting lying – including highly experienced financial analysts.

    But what would happen if we all had access to AI-powered technology on our phones that could spot deception with a high degree of accuracy? Would that change how the industry behaves?

    This is no idle speculation – in this episode of Decision Nerds, we explore research that suggests that AI is significantly better at spotting lying than humans. And as we all know, AI has a habit of surprising us by appearing in the wild far faster than we might expect.

    How would this technology impact the investment industry? We discuss:

  • Underperformance - everyone's got a plan until they're hit in the face
    Apr 23 2024

    𝗛𝗼𝘄 𝗺𝘂𝗰𝗵 𝘁𝗶𝗺𝗲 𝗱𝗼 𝘆𝗼𝘂 𝗴𝗶𝘃𝗲 𝗮𝗻 𝘂𝗻𝗱𝗲𝗿𝗽𝗲𝗿𝗳𝗼𝗿𝗺𝗶𝗻𝗴 𝗶𝗻𝘃𝗲𝘀𝘁𝗺𝗲𝗻𝘁 𝗺𝗮𝗻𝗮𝗴𝗲𝗿?

    1. Hire a manager after a period of strong performance.

    2. Watch in horror as you don’t experience that outcome, maybe the opposite.

    3. Spend a huge amount of time and emotional labour deciding on whether your initial thesis was wrong, something has changed at the manager, or with market dynamics.

    4. After sucking up a huge amount of governance time, decide to sack the manager.

    5. Rinse and repeat with potentially similar outcomes.


    Now that might not be you, but it is a story that plays out regularly.


    Experiencing underperformance is one of the unavoidable realities of hiring an active manager. And it’s painful for everyone; clients, managers and advisers. And badly managed pain creates some predictably bad outcomes for all parties.


    One important and manageable issue is time horizon mismatch. And this is what and I explore in the latest episode of Decision Nerds. We discuss


    𝗪𝗵𝘆 𝗶𝗻𝘃𝗲𝘀𝘁𝗺𝗲𝗻𝘁 𝗲𝗱𝗴𝗲 𝗶𝘀 𝗻𝗼𝘁 𝗲𝗻𝗼𝘂𝗴𝗵 – managers need an appropriate amount of time to let their edge play out. It may be longer than you think.


    𝗧𝗵𝗲 𝗕𝘂𝘅𝘁𝗼𝗻 𝗜𝗻𝗱𝗲𝘅 – a simple way of articulating time frames that would help everyone.


    𝗘𝘃𝗲𝗿𝘆𝗼𝗻𝗲 𝗵𝗮𝘀 𝗮 𝗽𝗹𝗮𝗻 𝘂𝗻𝘁𝗶𝗹 𝘁𝗵𝗲𝘆 𝗮𝗿𝗲 𝗵𝗶𝘁 𝗶𝗻 𝘁𝗵𝗲 𝗳𝗮𝗰𝗲 – we posit that most people’s ability to predict how they will deal with the pressure of underperformance won’t reflect reality when things get tough.

    We talk about the distinct behavioural pressures facing clients, advisers and managers and what they might consider doing to make things easier. A couple of takeaways if you don’t have time to listen.


    𝗖𝗹𝗶𝗲𝗻𝘁𝘀 - what is your real capacity for tolerating underperformance, how do you know this?

    𝗠𝗮𝗻𝗮𝗴𝗲𝗿𝘀 - have a clear view of the timeframe your results should be judged over. Whilst this a tough problem, if you don’t have a view, one will be forced on you.

    𝗔𝗱𝘃𝗶𝘀𝗲𝗿𝘀 - is your role to be a behavioural bulwark and help clients through this period, or just keep them happy? They are not always the same thing.

  • The other F word
    Feb 20 2024

    Thinking and talking about failure can be tough, especially when it’s us who’s failing. But it’s important for us as individuals and investment teams to find a way to do this in an effective manner that allows us to both learn and evolve. In this episode of Decisions Nerds…

    - Joe pits his inner Brian Blessed against an AI auto-editor

    - We examine Joe’s framework for thinking about errors around investment beliefs, processes and outcomes.

    - We then think about this in the context of broader research that thinks about different typologies of errors; basic, complex and intelligent.

    - We then discuss the practical steps that can make life easier.
