Objectivity is a way of thinking in philosophy that means that, when it comes to ideas about the world, you should form your own opinion based on facts and data, instead of relying on what other people have already said or what your own personal beliefs might be. For example, if you are studying a certain topic in school, you should look for trustworthy sources of information and not just listen to what your teacher, friends, or family say about it. Objectivity means that you should consider all of the evidence, both positive and negative, before forming your own opinion about it.
