The data confirmed your expectations? That’s great, you were right from the beginning – or where you tricked by what is called confirmation bias – you only saw what you wanted to see? Although the effect is typically strongest with emotionally charged subjects (think gun control), it can be a serious problem in scientific experiments
I have a new paper published on nest-defence in Acromyrmex leaf-cutting ants. We found that young virgin queens switch to worker behaviour once they lose the prospect of founding their own colony. Normally, virgin queens avoid taking risks because they are supposed to partake in a mating flight and found a new “daughter” colony afterwards.
