CRITIQUES, RULES, AND NOTES
Be aware of the following rules before posting comments:
- Please do not post summaries of the video in the comments - it damages retention on the video and YouTube is less likely to promote it (these videos cost me a lot of money to produce).
Critiques of my work are welcome! Please be aware of the following notes & rules before submitting critique:
Be mindful that this content is not all encompassing on the subject at hand and is self-limited for brevity to reach a wider audience. Also, be aware that I receive hundreds of YouTube comments per day, so the only way your critique can be considered is if you follow the steps outlined below. Finally, YouTube auto-deletes links, so I do not see most comments with links attached.
RULES:
If your comment is rude, you will be banned.
If your comment is not about the studies/topics at hand (i.e. extending to other outcomes not discussed) or offers critique with no scientific basis, it is unlikely to receive a response.
If you can follow these rules, I will try to address your critique and if there is merit, I will add an AMENDMENT to the content in question and pin it so everyone can see it (thank you!).
