We did an experiment at work.

Half the group was asked if they thought a person was above 165cm tall, which he was.

The other group was asked if they thought the same person was below 190cm, which he also was.

Then after, both groups were asked to guess his height. The second group guessed significantly higher than the first. Since both groups were told a number first, their response got anchored/biased towards that value.
