This work is in line with work that opts for an "ecological rationalism" combined with an Ethics of climate change encouraging cognitive progress. We want to highlight a particular dimension related to cognition (orientation). By rehabilitating statistical tools such as "correlation, both the concept and the coefficient", and using one of the most user-friendly and easily understood ways of presenting correlation for non-statisticians (expectations table), can we project ourselves into the future? End if so, what sould be the quality of the candidates who will manage the actions that will be taken against the climate change ? A priori, it suffices to submit our future managers of climate change to an Ecological Aptitude test knowing their Climatic Performance to be sure that we are on the right track of a long path leading us towards sustainable development.
