You didn't make the distinction because you wanted to convey the sophist argument that because the poll was conducted on the internet, it's not credible because of other internet polls that don't require registration or authentication. It's a subtle thing you're doing, but you're still doing it.
Would you say that a random poll on JPP has the same credibility as a poll conducted by YouGov?
So once again, you are exercising sophistry. I didn't say the poll was the same as Facebook. What I said was that the polling YouGov does, which you said yourself is scientific, is not like the polling you would see on Facebook or Twitter. Polls on those sites, that don't require authentication or registration, I would agree aren't credible because bots can just spam them. But a YouGov poll cannot be spammed by bots. That's the distinction you're not making. By broadly saying a poll that was conducted on the internet is not credible, you are making the argument that all internet polling is the same (there's that BoTh SiDeRiSm), therefore we should not accept it. But not all internet polling is the same, is it? In the case of YouGov, they don't just put a poll in a Tweet or Facebook post...they randomly select from their pool of registered poll takers, which means they have to actually take the survey, which also protects against spamming and bots (*I am not a bot* boxes, etc.). No different than a pollster randomly selecting phone numbers from vast lists of numbers of people who signed up to be polled (or whose information was just handed to pollsters in a bulk purchase).
And also, polling over the phone takes even less time than these YouGov polls. I was polled in 2017 during the Special Election in GA. It took less than 1 minute.
Your argument is that because the poll is conducted over the internet, means it's not credible (despite you saying it was scientific).
Not sure why you think that, but the only conclusion we can come to is that you think YouGov's polling is the same as unauthenticated and/or unregistered push polling that you regularly see on platforms like Facebook, Twitter, or even JPP.
You can't spam a YouGov poll.
