Science must be open and aim for the common good. Scientific advancement is done to provide well-being to the population and to facilitate the way in which this population lives, moves, communicates and reinvents itself. As the population is constantly changing, it is necessary that scientific thinking be open to these changes as well.
Social changes, climate change, behavioral and food changes shape current scientific thinking. The advancement of technology is possible, thanks to the human being's ability to change. We can use several examples that prove the need for scientific thinking to be open to change. Among these examples are the changes in the media, the change in scientific thinking about how the human being should communicate has promoted a breakthrough in the technology that has resulted in smartphones, applications and computers that have so much changed the way we communicate.
Another example is the methods of treating diseases, each time disease becomes stronger, more difficult to treat and more common, scientific thinking has to change to formulate treatments more effective and less devastating.
