Biology
Biology is the natural science that studies life and living organisms, including their physical structure, chemical processes, molecular interactions, physiological mechanisms, development and evolution. Chris has talked a lot about biology and therfore fails hardest at it. Chris surprisingly accepts biological facts such as evolution and vaccines which many Christians reject though he has the facts jumbled up and ends up speaking nonsense most of the time.
Reproductive biology
He mixed up his knowledge of the human sperm and egg, he thinks the sperm count is a fixed number that goes on decreasing every time he masturbates. This would have been much more horrific if Chris was a biological female and drank his menses. This culminated in him drinking his own semen to keep his sperm count high. He also believes keeping semen inside his refrigerator will keep it viable, the only thing this will do is give him more Cwcsicles to use in his Fanta.
Chris also thinks that transgender woman can get periods which he learnt from a facebook post. Unless Chris is bleeding from his asshole due to ramming medallions, Chris physically cannot get a flow of menses. Abdominal cramps are common for biological women during periods; for MTF women, this again is physically impossible due the lack of a uterus. Feeling under the weather is also a common symptom of periods, Chris claims he gets these but these are caused due to changes in specific hormones released by the female brain and uterus in conjunction.
Unless Chris is changing the dosage of his hormones to feel depressed, he is just imagining the symptoms.
Chris also believes after his gender reassignment surgery is complete, he can get pregnant. He also believes listening to certain subliminal hypnosis beats can help him sprout a vagina and uterus. After a while of listening to the subliminal frequency, he thought his pubic symphysis is a vulva and sliced open his taint. This not only showed how much belief he has in pseudoscience but also proved he has no knowledge of female anatomy whatsoever.
Neuroscience
Chris rejects the existence of asperger's syndrome though it is a well proven syndrome in the scientific community. He thinks that people with aspergers steal the limelight from people with autism though this doesn't make any sense since both of them are incredibly similar and on the same spectrum. Chris believes that the mind and body are separate entities where the mind can move between different bodies I.e the body is nothing more than a vessel for his mind. This has never been proved and most research points to different inter-neuronal connections being the reason for different personalities.
Immunity
During the COVID-19 pandemic, Chris watched the Cells at work anime to boost his immune system, whatever that meant.
