Online Certificate in Critical Thinking

Critical thinking is a technique that helps to evaluate arguments, their consistency, veracity and plausibility. In an age of information overload, it is important to identify which information to trust and what to discard. Many believe in what others tell us, without questioning the source or asking for proof. Learning how to think critically is a cross disciplinary skill, useful not only for those working in science, but also for people interested in ethical reasoning and decision making, information management and even in our daily routines.

Critical thinking helps is to assess what advertisers are telling us is acceptable and or how biased is the information provided by the media or governments. Critical thinking protects us from being manipulated, helping us to identify flawed reasoning and badly constructed arguments. It is a crucial skill to have in modern times.

To answer these needs, CEI created an Online Certificate in Critical Thinking where each new course builds on the previous one. For detailed information about the structure of the certificate download the brochure by clicking on the image.
