"La falta de datos es una fuente importante de incertidumbre no de teoría"

Simplified Meaning:

When we don't have enough information or facts, it's hard to be sure about things. This happens not because we don't have good ideas or explanations, but simply because there's not enough data to prove or disprove those ideas. For example, imagine you're trying to bake a cake for the first time, but the recipe is missing key details like how long to bake it or at what temperature. Even if you have a general idea of how baking works, you might be unsure about how your cake will turn out because you don't have all the necessary information. In history, scientists often had theories about how diseases spread, but without proper data and research, there was a lot of uncertainty about these theories. It wasn't until detailed studies and experiments were conducted that they could be more certain about their ideas. So, when facing uncertainties in life, gathering more information and facts can help clear up doubts and make more confident decisions. For example, if you're unsure about which job to take, collecting detailed information about each opportunity can help you make a better choice.
