### Languages

All datasets are in English

## Dataset Structure

### Data Instances

#### cognitive-bias

An example of one training instance looks as follows. 
```json
{
  "text": "A defense bill includes language that would require military hospitals to provide abortions on demand",
  "label": 1
}
```




### Data Fields

- `text`: a sentence from various sources (eg., news articles, twitter, other social media).
- `label`: binary indicator of bias (0 = unbiased, 1 = biased)




## Considerations for Using the Data

### Social Impact of Dataset
We believe that MBIB offers a new common ground
for research in the domain, especially given the rising amount of
(research) attention directed toward media bias
