Keith Burghardt's Abstract:
Heuristics are pervasive in our day-to-day life. These “rules of thumb” such as assuming popularity is synonymous with importance (e.g., the Bandwagon effect), reduce cognitive load but can also nudge people to unexpected and suboptimal outcomes. In this talk, I will show examples from my own research of how these simple rules of thumb show up repeatedly, and can negate many benefits otherwise apparent in crowdsourcing and recommendation systems. First, I will show that heuristics make finding quality content on crowdsourcing sites more difficult, but this can be mitigated with a simple algorithm. Next, I will show evidence that heuristic-based data, when fed into recommendation systems, can enhance polarization and allow for hate groups and misinformation to proliferate. Finally, I will conclude with suggestions on how correcting for these biases may make better AI systems.

Keith Burghardt's Bio:

Burghardt is a computer scientist at the USC Information Sciences Institute who specializes in understanding human behavior with physics-inspired models. Burghardt received multiple awards including a 2015 Conference on Complex Systems Starred Paper award and a 2016 ISI Director’s Intern Award. Burghardt organizes the USC/ISI AI Seminar series, and has organized the S3B2-ML Summer School and CKIDS student research projects. Burghardt received a BS in Physics (Magna Cum Laude with High Honors) and PhD in Physics at the University of Maryland in 2012 and 2016, respectively.
