Another reason might be what I think
psychologists refer to as ‘recency effect’. In first year psych (17 years ago) I seem to remember it being said that when we see a long line of people or things and are then asked to make a judgement we will typically best remember what we saw first (primacy) and what we saw last.
Going last might have been an added blessing for Kurt. and it might have been a factor in Guy Sebastian’s poorer than expected result.
