Everything that is expressed and recorded externally, such as cell phones, computers, memos, books, and drawings, is an extension of the brain. Our brains aren’t just inside our bodies. This concept is important because extending the ego greatly influences how we see the world. We pay close attention to topics that involve us personally. Self-relevance is a key factor that drives our lives. Personal relationships and possessions get a lot of focus, while other areas seem less important. This is due to a feature of the human brain called ‘selective cognition.’ As civilization advanced, humans delegated parts of the brain’s functions to machines. It was inevitable to make good use of these tools. We should take an interest in the Homo Faber. - Joseph’s “just my thoughts”
The social scientist’s method of confirming the facts is first to verify the beta error (Type II error) and then the alpha error (Type I error) before accepting the hypothesis as true. In other words, if the probability is less than 5% after focusing on the likelihood of accepting a false hypothesis as true (Type II error), then we risk rejecting a true hypothesis (Type I error) as false. It’s a conservative position that new information will be accepted only when the probability of being wrong is very small. This verification method is helpful if you don’t want to be swayed by conspiracy theories. - Joseph’s “just my thoughts”
