Step-by-step explanation:
Identifying the author's intended audience in “Heads Up, Humans” involves understanding the context and the content of the writing. From the given excerpts, it seems that the primary audience consists of people interested in human personality and psychology, particularly those who are receptive to communication that challenges typical patterns of thought. The author's reference to the “Do the Math survey” and personality types suggests that individuals curious about or educated in psychology (especially enthusiasts of the Myers-Briggs Type Indicator) make up the primary audience. The secondary audience might include educators or communicators looking to broaden their reach by adapting their methods to various personality types.
This approach to identifying the audience emphasizes the need for awareness and adaptation in communication strategies. The author suggests that by being more inclusive of different personality types, the message could have a broader impact. In terms of additional or secondary audiences, these could be people outside of the psychology community who might benefit from learning about how communication styles can better accommodate various personality types, or those involved in education or advocacy who need to communicate important messages to a wider audience effectively.
