Fact-checking

The data used for creating the Twitter dataset is obtained from the Poynter Coronavirus Fact Alliance. The alliance consists of 101 fact-checking organisation based in 749 countries and covering 48 languages.

The largest amount of fact-checked content comes from English (7,002 fact-checks) and the least is Finland (1 fact-checks). Most fact-checked content is in Spanish (3,816) followed by Portuguese (2,333) and Ukrainian (1,335) (Figure 3).

Determining a direct impact of fact-checking on the spread of misinformation is not easy. However, it is possible to determine how well a particular corrective information is spreading in relation to its corresponding misinformation.

Figure 5 shows how misinformation and fact-checking content has spread in various topics for the last two analysis periods and overall.

Demographic Impact

Figure 6 displays how misinformation and fact-checks are spread by different demographics.
