These newer methods are different enough from the methods that caused problems in the past that I think it makes sense to think of them as“non-probability sampling 2.0.” The second reason why researchers should reconsider non-probability sampling is because probability sampling in practice are become increasingly difficult.
probability samples and non-probability samples are not as different as many researchers believe.
Sometimes, researchers have found that probability samples and non-probability samples yield estimates of similar quality(Ansolabehere and Schaffner 2014), but other comparisons have found that non-probability samples do worse(Malhotra and Krosnick 2007;
far from the theoretical results that justify their use- and non-probability sampling methods- which are cheaper
the particular version Wang and colleagues used is one of the most exciting approaches to weighting non-probability samples.
Sometimes researchers have found that probability samples and non-probability samples yield estimates of similar quality(Ansolabehere and Schaffner 2014), but other comparisons have found that non-probability samples do worse(Malhotra and Krosnick 2007; Yeager et al. 2011).

probability samples and non-probability samples are not as different as many researchers believe.
A clear example of how far we have come with non-probability samples is the research by Wei Wang, David Rothschild, Sharad Goel, and Andrew Gelman(2015) that correctly recovered the outcome of the 2012 US election using a non-probability sample of American Xbox users-a decidedly nonrandom sample of Americans.

Not all non-probability samples are the same.
Probability Sampling vs. Non-Probability Sampling.
The alternative to probability sampling is non-probability sampling.
Bit By Bit- Asking questions- 3.4.2 Non-probability samples: weighting.
Seems to do a good job correcting the biases in non-probability data;

Seem to do a good job correcting the biases in non-probability data;
Probability samples and non-probability samples are not that different in practice;
Non-probability samples need not automatically lead to something like the Literary Digest fiasco.
