I am very excited to talk about the Big Team Psychology, foundational tests, and the Many Smiles Collaboration at #PSACON2020 tomorrow!

For those who cannot attend, here is a [THREAD]!

In the talk, I will be focusing on the role of Big Team Science in my own research on a controversial idea known as the facial feedback hypothesis (the idea that posing facial expressions of emotion can impact our actual emotions).

Conflicting evidence from (1) a large-scale replication effort and (2) a meta-analysis on the facial feedback hypothesis shed light on their respective epistemological limitations.

Debates over theorized effects often cannot be settled by either approach!

I argue that crowdsourcing the design of *foundation tests*—tests w/ condition highly favorable to the emergence of theorized effects—can (1) accelerate the identification and resolution of theoretical disagreements and (2) make failures to observe effects highly informative.

We designed a foundational test of the facial feedback hypothesis in the global, adversarial, *Many Smiles Collaboration*. Preliminary results suggest that facial feedback does influence emotion, but we are still awaiting results from our global sample. (COVID-19 delayed us.)

I will end my talk tomorrow with a discussion of my future vision for Big Team Psychology…

I aspire to move crowdsourced science beyond the pooling of data collection resources

The biggest problems in science require many minds. But Big Team Psychology is often led by the minds of a few. I believe enormous growth could occur if we pooled our *intellectual resources*

I argue that the @PsySciAcc is particularly well-positioned to pool intellectual resources to spur enormous theoretical growth in psychology and build a better science.

Let’s get to work!
