*''The attempt to reach a representative set of user data'' is the key differentiator between the approaches. In standard surveys one can easily see that the responses of those who offer or volunteer to take a survey are likely to be quite different from these of a rigorously administered survey. Such self-selection bias is a key weakness of online data collection also. | *''The attempt to reach a representative set of user data'' is the key differentiator between the approaches.

* Those users who would normally not participate, if they were asked, do not wish to participate. So, the difference between opt-in and opt-out is that opt-out includes many of those users who do not wish to participate, therefore violating their wishes and rights. | |||
* So, if the argument is that the result data will be different, then yes, it will be different, because it includes those users who do not wish to be included, but are included anyway. | |||
* If fact, if they actually do opt-out, then the data would be different again, therefore the same argument of "statistic is biased" applies. If the argument is that opt-out has average data, then only because many user wishes are violated. | |||
* The argument "if they don't want to, they can opt-out" is a fallacy, because most users will not know about this data gathering. They cannot opt-out, if they don't know about it, because they have never been asked. | |||
* This is why European and German law *requires* opt-in for any gathering of data about the user. | |||
