Name of cognitive bias where people try to use all given information regardless of quality? In psych class, I recall learning about a cognitive bias where people are inclined to use all information available to them when making a decision, even if some of the information would be better ignored.

I believe the example given was a study in which participants were asked to evaluate the (college?) application of a candidate. Some participants were given just the conventional application information, while others were additionally given irrelevant information in the form of a portfolio of the candidate's elementary school artwork. The finding was that the artwork influenced the participant's decisions when it was provided.

What I don't remember is what this bias is called!
It's probably related to information overload "the difficulty in understanding an issue and effectively making decisions when one has too much information about that issue". As for a more specific term...

In the full text of https://doi.org/10.1207/s15327663jcp1403_7 it's called the irrelevant attribute effect. I'm not sure how widespread this term is. Therein it's defined as the scenario when


  irrelevant information may influence choice even when there is an easily
  justified basis for choice other than the irrelevant attribute.


There are a lot papers out there on how irrelevant information affects choice, but most don't seem to use this precise term but some reasonably close expression.

There's even one paper which discussed a sub-form of this, namely the dilution effect, which


  occurs when a person’s consideration of irrelevant information leads to a less extreme judgment. 


Even though it's narrower in meaning, this last term is more widespread.
