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 1000 countries and covering 46 languages.

The largest amount of fact-checked content comes from English (8,706 fact-checks) and the least is Finland (1 fact-checks). Most fact-checked content is in Spanish (4,577) followed by Portuguese (2,801) and Ukrainian (2,073) (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.
