In today's pop culture, there is one very popular view of the future. All humans will be free to do as they wish, because robots and computers will work for us.

It is the repercussions of this behavior that cause the error, because the person is not using his/her senses properly. In conclusion, it is understandable that humans make mistakes despite the fact that our senses receive sense data from objects surrounding us.
