How much decision noise is there in financial advice?
A lot, as it turns out!
Oxford Risk has launched a landmark study of human noise and inconsistencies in the advice process.
Research conducted for Momentum Investments and with The Financial Planning Institute in South Africa is the first of a number of such studies.
Human advice, whilst invaluable, is (it turns out) also extremely inconsistent. This clearly demonstrates the need for behavioural decision-support tools to assist advisers in being more consistently the best versions of themselves... every day, and for every client.
What is noise, and why should we care about it?
The most suitable investment solution should depend on the investor circumstances it’s recommended for, not the adviser that’s recommending it.
Consistency of advice is a crucial concern for any firm. If what is deemed suitable for a client can differ depending not only on which adviser within a firm they speak to, but also on the prevailing mood of a particular adviser, then that firm has a problem. Especially when we remember that advice isn’t a single event, but an ongoing relationship, and that the regulations care not whether you get it right on average, but whether you get it right for each individual.
The two main sources of inconsistency in advisory processes are an overreliance on humans, and the heavily front-loaded nature of suitability assessments.
The aim is not to turn advisors into algorithms. Humans are wonderful at many things. But they are inefficient and unreliable decision makers, especially where many moving parts are involved – as in Risk Capacity. Humans are prone to ‘noisy’ errors – unduly influenced by irrelevant factors, such as their current mood, the time since their last meal, and the weather.
Noise isn’t bias. Bias is systematic: it errs the same way every time. Like a mapping model that puts every client into too risky a portfolio.Noise errs in more mysterious – and therefore less easily manageable – ways.
Upfront assessments are necessary but insufficient, and often overplayed. Suitability reflects circumstances. Circumstances change.Constantly. Sometimes changes are imperceptible. Sometimes pandemics happen.Because this is inherently complex, we are drawn towards the sanctuary of the status quo. Overemphasising initial assessments makes investment solutions over-fitted to the investor’s circumstances at that single point in time, and unresponsive to subsequent changes. They drift away from what is suitable over time. And in times of crisis this drift can become a dash.
Because Risk Tolerance is a single, largely stable, and easily quantified attribute, it is regularly weighed too heavily in determining suitable solutions. Suitability should be more responsive to Risk Capacity – especially during an investment journey.
But Risk Capacity has many moving parts. Studies on multi-attribute decision-making show that even when people think they’re assimilating evidence from all sources, they’re really just filtering down to the few that stand out. And that few isn’t consistent over time, let alone over different decision makers.
Establishing frameworks to drive consistency in diagnosing situations doesn't mean giving every client the same answer. It means those answers need to be within boundaries defined by a clear diagnosis of the problem. There are multiple paths towards remedying any situation, depending on client personality, circumstances, and engagement.
Identifying noise isn’t about eradicating inconsistencies. It’s about eradicating unjustifiable ones and evidencing justifiable ones.
