How will COVID-19 impact NEGATIVE affect on social media in 6 months (Oct 2020)?

The Behavioral Forecasting Collaborative organized by researchers at the University of Waterloo has been studying positive and negative affect (i.e. emotions) on US English-language Twitter data. Their research methods are as follows:

Estimates for NEGATIVE affect were calculated by applying a custom lexicon to message unigrams. The estimates provide the monthly sum of the pointwise mutual information of each unigram with positive and negative affect theme. The scores quantify the extent to which the monthly tweets contain language that is associated with negativity.

We standardized estimates based on all prior time series data (M = 0.145 / SD = 0.0215), maintaining difference between the groups. Here, unit of change reflects standard deviations above or below the average of all prior data (Jan 2017-Mar 2020) for both positive and negative affect language.

Recently, they have expanded their research to include a new interest in how COVID-19 affects positive and negative affect on social media. This question asks:

What will the negative affect score value be on social media, for October 2020?

We will collect predictions until May 22nd as part of a tournament, and this question will resolve mid-November, according to the dataset available on their website.

Metaculus help: Predicting

Predictions are the heart of Metaculus. Predicting is how you contribute to the wisdom of the crowd, and how you earn points and build up your personal Metaculus track record.

The basics of predicting are very simple: move the slider to best match the likelihood of the outcome, and click predict. You can predict as often as you want, and you're encouraged to change your mind when new information becomes available.

The displayed score is split into current points and total points. Current points show how much your prediction is worth now, whereas total points show the combined worth of all of your predictions over the lifetime of the question. The scoring details are available on the FAQ.

Note: this question resolved before its original close time. All of your predictions came after the resolution, so you did not gain (or lose) any points for it.

Community Stats

Metaculus help: Community Stats

Use the community stats to get a better sense of the community consensus (or lack thereof) for this question. Sometimes people have wildly different ideas about the likely outcomes, and sometimes people are in close agreement. There are even times when the community seems very certain of uncertainty, like when everyone agrees that event is only 50% likely to happen.

When you make a prediction, check the community stats to see where you land. If your prediction is an outlier, might there be something you're overlooking that others have seen? Or do you have special insight that others are lacking? Either way, it might be a good idea to join the discussion in the comments.
