Decision-making Under Adversity - By Amanda Blesing and Russell Boon

Learning how the brain interprets and processes stressful situations can help the decision-making process in high-pressure environments

We initially became interested in decision-making as a topic because of insights and evidence from the gender diversity debate. Organisations with both women and men on the leadership team in relatively equal numbers perform better on a range of measures including profitability, productivity, risk, customer satisfaction and staff engagement. And the reasons why? Researchers put it down to better decision-making:

  • ‘companies with strong female leadership deliver a 36 per cent higher return on equity, according to the index provider MSCI’ (World Economic Forum, 2015)
  • ‘companies ranked in the bottom quarter in terms of gender diversity on their boards were hit by 24 per cent more governance-related controversies than average’ (World Economic Forum, 2015).

However, women are frequently criticised for their decision-making. They’re allegedly slower at making decisions, wanting more evidence and are more risk averse. This is seen as a negative by organisations that are used to more masculine models of leadership.

On the flipside, we know that testosterone drives a bias toward action, competitiveness and risk taking, so men tend to make decisions faster. However, a too-fast decision isn’t always a better decision, and certainly a too-slow decision doesn’t get anyone anywhere fast. Additionally, when stress, anxiety or fear is added into the mix, no one is great at making decisions. In fact, we’re wired to bypass the logical parts of our brain when under pressure, which makes great decision-making really challenging.
