Cognitive distortion refers to patterns of biased or distorted thinking that can lead to negative emotions, behaviors, and beliefs. These distortions are often automatic and unconscious, and can affect a person's perception of reality and their ability to make sound judgments.

Some common types of cognitive distortions include:

Personalization: Blaming oneself for things that are outside of one's control.

Examples:

She looked at me funny, she must be judging me.
I can't believe I made that mistake, I'm such a screw up.

Emotional Reasoning: Believing that feelings are facts, and letting emotions drive one's behavior.

Examples:

I feel like I'm not good enough, so I must be inadequate.
They never invite me out, so they must not like me.

Overgeneralizing: Drawing broad conclusions based on a single incident or piece of evidence.

Examples:

He never listens to me, he just talks over me.
Everyone always ignores my needs.

Labeling: Attaching negative or extreme labels to oneself or others based on specific behaviors or traits.

Examples:

I'm such a disappointment.
He's a total jerk.

Should Statements: Rigid, inflexible thinking that is based on unrealistic or unattainable expectations of oneself or others.

Examples:

I must never fail at anything.
They have to always put others' needs before their own.

Catastrophizing: Assuming the worst possible outcome in a situation and blowing it out of proportion.

Examples:

It's all going to be a waste of time, they're never going to succeed.
If I don't get the promotion, my entire career is over.

Reward Fallacy: Belief that one should be rewarded or recognized for every positive action or achievement.

Examples:

If I work hard enough, they will give me the pay raise I want.
If they don't appreciate my contributions, I'll start slacking off.

Model Description

This is one of the smaller BERT variants, pretrained model on English language using a masked language modeling objective. BERT was introduced in this paper and first released in this repository.

Data Description

[In progress]

Using

Example of single-label classification:

python

import torch
from transformers import AutoTokenizer, AutoModelForSequenceClassification

tokenizer = AutoTokenizer.from_pretrained("amedvedev/bert-tiny-cognitive-bias")
model = AutoModelForSequenceClassification.from_pretrained("amedvedev/bert-tiny-cognitive-bias")

inputs = tokenizer("He must never disappoint anyone.", return_tensors="pt")
with torch.no_grad():
    logits = model(**inputs).logits

predicted_class_id = logits.argmax().item()
model.config.id2label[predicted_class_id]
