Conquering the COVID-19 Infodemic: How the Digital Black Press Battled Racialized Misinformation in 2020
- In 2020, as many Black people around the world fought both anti-Black racism and COVID-19, the Black press in the US was dealing with another widespread problem: an infodemic. Editors of Black digital publications were on the frontlines of dispelling racialized misinformation about COVID-19, all while reporting on a contentious presidential election, ongoing protests for racial justice, and a rising COVID-19 death toll that disproportionately affected African Americans. This mixed-methods study—which includes semi-structured interviews in addition to website and social media analyses—explains the top five tactics that Black outlets used to serve as an advocate for, and an adviser to, their communities during its time of dire need. Their strategies provided an editorial slant that challenged anti-Black racism in public discourse and countered misinformation with factual public interest journalism.

- Driving 4 hours for a 2 hour meeting
- It went pretty well, but Dr. J was a no show. Everyone is very interested in MP-type stuff, so I think we should organize the DTA work to produce a demo along these lines, maybe within the context of the MDBE. That could look very fancy.
- Wrote up a easy to read Monte Carlo Markov Chain description.
- The big use for NNMs (that no one can grok) is the visualization and prediction of mismanagement. It’s all people talk about in these places.
Markov Chain Monte Carlo: Exploring Probability Through Random Walks
Imagine you’re trying to figure out how effective a new drug is at treating a disease. The traditional statistical methods might not work very well because the problem is too complex – there are just too many factors to consider. This is where Markov Chain Monte Carlo (MCMC) can really shine.
MCMC is a powerful technique that combines two key ideas: Markov chains and Monte Carlo simulations.
A Markov chain is a sequence of events where each step only depends on the previous one. It’s like a random walk, where your next move is based only on where you are now, not on your whole history.
Monte Carlo simulations, on the other hand, are all about playing with randomness to find answers. Instead of trying to calculate everything exactly, you take a bunch of random samples and use those to estimate what you want to know.
Put these two ideas together, and you get MCMC. The basic process is:
- Start with an initial guess about the drug’s effectiveness.
- Take a small, random step from that starting point. This step represents the uncertainty or noise in the data.
- Decide whether to keep this new guess based on how well it fits the data you have. The better it fits, the more likely you are to accept it.
- Repeat steps 2 and 3 many, many times.
Over time, as you keep taking these random steps and accepting or rejecting them, your guesses will start to converge towards a meaningful result. This convergence is key – it tells you that the MCMC process has thoroughly explored the probability distribution and found a stable estimate.
MCMC is really powerful because it can handle complex models and uncertainties that would be very difficult to deal with using traditional methods. In our drug example, MCMC could help you estimate the drug’s effectiveness while accounting for all sorts of factors like patient characteristics, side effects, and so on.
The great thing about MCMC is that it’s flexible and can be adapted to all kinds of research problems, from predicting disease progression to optimizing drug combinations for cancer treatment. By leveraging the power of random walks and probability, MCMC can turn complexity into clarity and uncertainty into insight. It’s a truly remarkable tool in the researcher’s toolkit.
