Lie Spy was developed and is run by me, Geoff Muskett. I value honesty, which feels like it has been in short supply from our politicians.

I’m a web designer, this is my way of trying to make sense of politics when we don’t know who to trust.

How truthful are politicians in reality? Maybe they’re not as bad as we think. Or maybe they are. Maybe certain parties are more truthful than others.

Let’s try an find out in an impartial way as we can.

The BBC’s Reality Check and Full Fact are great resources. I look at these and sometimes other places for research.

Then take the claims politicians or parties make and give them a rating based on my interpretation of the fact checking.

No cherry picking of claims, like it or not I post it.

Links to the research accompanies each claim posted.

All ratings can be disputed. I aim to be fair.

Rating philosophy

Each claim is rated from 0 to 5 (though they’re represented as a percentage bar). 5 being the truth.

Claims that are outright “I, Bill Clinton, didn’t have relations with that woman” lies, in which case they’re given 0.

If there’s an element of truth in a claim, the size of this element depends on whether the score is 1, 2, 3 or 4.

I find that claims politician make are often technically facts. However they may leave out key information. In my book that is misleading so we can’t give it 5 out of 5.
