Is online crowdsourcing a legitimate alternative to lab-based research?

Here are some helpful papers making the case for online crowdsourcing:

1. This paper shows that online crowdsourcing can be legitimately used for collecting data, and that it allows to collect high quality data inexpensively and rapidly.
2. Here's a paper showing that results from a lab experiment were indistinguishable when replicated online.
3. Here's a more nuanced perspective on lab vs. online experiments: some effects replicate online, others don't.
4.  This one is a great example of a high-impact paper published in the journal Nature using MTurk samples.
5. Finally, this new paper shows that Prolific is better suited for scientific research than MTurk.
