[@rosieharrison949]

You are officially my math tutor! I'm so glad I found you two weeks ago!

[@Simplelearningpro]

Thank you for your comment :)

[@user-bz7fj1fk2m]

Note that you are delighting young minds of the world with excellent conceptual explanations. STAY BLESSED!!!!

[@Simplelearningpro]

Thank you so much for your comment, Alem!

[@shafiuusmanmaitoro1291]

This is one of the best explanations I have ever had on placebo treatment. Keep it up

[@Simplelearningpro]

Thank you for your comment! It inspires me to keep making more videos. Feel free to support me on patreon as it would help me a lot

[@jayozigbo2235]

After studying for my MBA with over 70K tuition per year. My statistics professor could not explain this very well

[@MonkeySpecs301]

you should of just moved to the west coast if you aren't out here alredy and bought a property and grown weed, would have been easily milliionaire a few times over.

[@ゆうちゃん-b9j]

nice!

[@r4gequ1t_cya]

Clear and simple, pretty straightforward. Love the art style too they're cute hehe

[@Simplelearningpro]

Hehe thank you :)

[@mrcooper8310]

This was very good and clear thanks

[@Auntie_Joker]

indeed @stas anastasiou... Its really clear. But nowadays many researchers did single blinded experiment, just to make sure that they achieve what supposedly the want to.

[@RedHatcc]

totally agree... 101 and very clear

[@SavageSwan25]

uggghhh finally the clearest explanation ...far clearer than my instructor... Thanks for this!

[@niveditasahu5265]

THANK YOU SOOOO MUCH. Last minute saviour.... Its all coz of u i could complete my presentation. Keep uploading videos like this. ONCE AGAIN THANK YOU

[@gathsayuriperera7814]

This explanation is perfect.

[@الطائرالجارحاسيرالظلام]

Thank you so much.. I really appreciate you excellent explanation

[@keshavkesuu]

3:25 if both of them doesnt know which group is which then it is possible to have the get the comparative data and how can one understands whether the Placebo medicines worked or not

[@ACitizenOfOurWorld]

Someone will know. perhaps the pills were give a number code that only the person who made the pills knows. Then at the end of the experiment, everyone finds out the number on their pill represents the placebo or real medicine.

[@_ecabels]

THIS HELPS ALOT THANK YOU!!!!!!!!!!!!

[@shannalotzgeselle9536]

Thank you for your information. This is why I am declining the Covid vaccine at this time. I consider myself part of the control group!

I'm Lucky that I found you it's a bit late but on scale for my sem xams thank u

[@shaneatkinson8933]

lol i slightly understand now . . .im dyslexic . . .study for my masters in Mental health: psychological therapy .....thank you smart man

[@OldMovieRob]

This was helpful. I'm curious: when they test out vaccines, do they also do these as placebo/double-blind experiments to check for any potential negative effects?

[@HCkev]

Yes. If a number of people get sick and all or most of them are in the experimental group and not in the placebo group, then we can tell this is most likely adverse effect of the medecine being tested. However, if there are about as much people who got sick in both groups, then we can attribute the adverse effect to other variables.

[@mahamudtarey7837]

many thanks, you cleared the dust cloud over me re difference and relations of those issues

[@pooja8140]

Thank you for this simple explanation!!

[@Simplelearningpro]

Glad I could help!

[@sad_doggo2504]

Self-reporting is also an issue. Could having independent, measurable variables (like, how much can a person lift after taking the pill or placebo) can make the test more stringent? I'm trying to learn about these methodologies to combat superstitious thinking. Thank you for uploading!

[@nikhilpawar7876]

Absolutely awesome explaination 🎉

[@shalmarhinds4117]

if I pass my exam I'm every video this person made 😍

[@ゆうちゃん-b9j]

facts me to

[@opinionsarentfacts412]

This might be a stupid question, but if the experimenters don't know who got what, then who does know? How do they know what the results are at the end of the experiment if they don't know who got what?

[@pavarotialman]

I dont know but I suppose there must be someone from outside the experiment that help the researchers with that

[@haideradab9010]

hhhhh i had the same question ....Its a smart question not stupid bro

[@DThorn619]

Ah usually there's a qualified third party that is authorized to know which group is which and such and only tells the researchers the results after the experiment is over.

[@palavardhanpeddapalegalla9265]

You have to understand more. There will be a guide for the researcher. He known that what pill has given to whom .

[@latestfortune3431]

this was very clear and simple to listen! thank you so much

[@cab711]

Even though the pill may present a statically significant result do you still have to demonstrate the reason why the change occurred?

[@yogeetabhattarai6753]

I'm kind of shocked as to how well you explained this. Did you go to school for this? Because I did. And your vocabulary and verbal demeanor is academically familiar

The double blind is so funny to me, but i get it thank you so much

[@victoriachuderska9469]

Question, if there is a double-blind method, how can we then analyse the results? Asking because I have an exam this Monday. Great explanation btw.

[@jessica._.Palmer]

I'm assuming that there's probably another person who knows who was given what

[@medilogic]

সেরা ❤️

[@MultiSciGeek]

0:43 That's actually the Nocebo Effect

[@ParadymShiftVegan]

Yeah but Nocebo and Placebo are both the same effect in principle. The only distinction is essentially whether we appreciate the results or not, but says nothing whatsoever about the underlying psychogenic mechanisms.

[@drhgbiology]

Great videos! Our institution requires closed captioning (not just auto-generated) for any videos we share with students so I cannot show them. :(

We are currently doing our best to work on them!

What's the difference between a blind experiment and a double blind experiment?

Thnkyouu 😘😘😘😘😘

[@Simplelearningpro]

No problem :) Thanks for commenting!

[@bluevalley82]

I’m the double blinded test, neither the patients nor the doctors know which groups the patients are and placebo or treatment they are receiving. Then who knows?

[@anav2434]

Thanks!

goat!!!!!

[@charliephoto]

Whis is this such a good way of teaching? 🤣

[@SG-jv5zi]

IF only they would do this to test the safety and efficacy of vaccines... Sadly, pharmaceutical companies production of vaccines (unlike every other industry) have NO liability and therefore no incentive to do ANY safety studies.

[@wetbread4243]

Ahhh so your an anti vax mom... I may not be able to get through to you but... The measles will

[@IIrandhandleII]

@@wetbread4243 this is how antivaxxers attack vaccines.. they try to pin side effects as caused by the vaccine because the efficacy of vaccines it's not questioned.

[@FA8072.]

the characters look so harmless and cute lol.

[@raydaveed]

The opposite is called "Nocebo effect"

[@Roks559]

I saw an ASAP Science video where they, in a clause, mentioned that a double blind experiment might some times be unethical. Why is that?

[@mehtabstudystreams]

Fakit the patient being tested may need the actual treatment but don't get it while expecting to.

[@doodle6004]

@@mehtabstudystreams They have to be aware that this is possible, otherwise it is unethical. Most research subjects sign extensive forms acknowledging that they're aware they might get the fake treatment. And they agree to this all the time. :-)

[@ParadymShiftVegan]

It just depends on what intervention you're testing. For example, we will never have double-blinded randomized trials for smoking being causally associated with lung cancer since it is considered unethical to deliberately bring potential death or great suffering to a person simply as collateral in pursuit of more articulate knowledge. edit grammar

[@DeFaulty101]

Actually, there's a different word for having a negative reaction to something simply because you believe you were going to; the nocebo effect.

[@ParadymShiftVegan]

Correct. On a tangentially oblique note, to the best of my knowledge, there exists no evidence suggesting any distinctions with respect to the implicit psychogenic mechanisms.
