The European Food and Safety Authority (EFSA) is currently running a survey on the topic of uncertainty, to improve the way that EFSA communicates and explains the scientific uncertainties related to its assessments. Even when there is strong evidence that something will happen, there will almost always be some uncertainty about the outcome, a point that should always be taken into consideration when taking decisions or making assessments. The survey should take about 10 minutes, and the participants are welcome to provide additional advice the topic.
