A suggested topic is whether you believe IQ testing (for job applications) should be allowed.

I believe that we should not use IQ testing for any job interviews/applications. Firstly, an IQ test is not a totally accurate depiction of one's true knowledge. IQ tests generally deal with the logical side of the brain, however a person born with a low IQ can still study and gain knowledge. As such, if IQ tests are used to determine if a person should get a job or not, the person with a higher IQ might not be as knowledgable on the subject as the one with a lower IQ.

Also, a job might require more than a high IQ. It highly depends on the scope of the job, and there are few jobs that require a high IQ for a person to excel in the job. Therefore, we should not have IQ testing for job applications and should stick to the conventional methods.

Which perspective on personalities makes the most sense?

It would have to be Sigmund Freud's perspective. His idea on the 3 parts of the mind, the id (responsible for our desires) aka the unconscious mind, superego which restricts our desires based on social norms and the ego which weighs all 3 psychic instances and chooses the best option.

I feel that this way of thinking of our brain is very logical as there are times when I am debating with myself on certain issues. This would seem to be the 3 instances working together to come up with the best solution for me.

However, his perspective also gives us one problem. If the id is the unconscious part of the mind, then how do we know about it, unless it is a guess. Which also means that we cannot prove that Freud's perspective is really true, as there are no ways to definitively say it exists. So, while it may make sense to apply Freud's thinking, there may actually be other reasons behind the way we think.
