HR and L&D professionals are increasingly at the heart of key decisions over resource and projects that significantly impact business performance and organisational culture. We are frequently asked to look at ways to improve business performance, yet knowing exactly what research, data or trends to trust is an incredibly difficult challenge. Getting things wrong over time has consequences, but working out how to get things right in the first place can be hugely problematic. Annoyingly and beautifully we are human. That means the evaluation process for new work - or continuing old work - is taking place within a thought process that is largely a bundle of biases and preconceptions. We all like to think that we are better at thinking through things logically than other people, this is because of something called the ‘Above Average Bias’ effect; it’s the same reason that most people think they are better than average drivers. Nobody likes to think they are making bad decisions and nobody likes to think they are wrong. That is a challenging starting point for working towards the truth.
