When Dr. Garth Graham thinks about health misinformation on social media platforms, he envisions a garden.

No matter how bountiful or verdant that garden is, even the head of YouTube’s global health division admits it’s often in need of tending.

“How do you weed and pull out the bad information?” he questioned.

“But also…how do you plant the seeds and make sure people have access to good information as well as high quality information?”

For social media companies, these have become perennial questions that have only grown in importance as the number of platforms multiplied and people began spending increasing amounts of time online.

Now, it’s not uncommon to spot misinformation with almost every scroll.
