is talking about investigation bias
because we're following a scientific process.
But because we're also human,
there are often times where we will make a preconception, as we talked about, an expert can put aside their preconceptions, but
you have tow. Have a new awareness
of the biases that you might have in order to
understand and fully appreciate
how to set aside your biases.
In this video,
we're going to talk about how to recognize and address Biasi in the investigative process.
So let's start off. What is bias
Bias is a disproportionate weight in favor of or against annoy, idea or thing, usually in a way that is closed minded, prejudicial or unfair.
As forensic examiners, we definitely don't want to
come in with a preconceived notion off what the outcome of a case is going to be,
and it's hard to dio. It's not an easy thing to Dio.
It takes a lot of practice, but what makes great experts are they're able to look at the evidence and not rush to judgment.
four really common
forms of bias.
Inherent bias, unconscious bias, confirmation, bias and halo or horn bias.
Inherent bias is everything we do everything that we look at. We've got an inherent bias.
You're gonna have biases based on your experience.
You're going to find something you're going to
by virtue of being a forensic examiner. Perhaps
you're have an inherent bias e for or against your,
the suspect in the cakes.
And you're gonna have an inherent bias See towards your client
the client that's hired you.
You want to either prove that they did or didn't dio that the suspect did or didn't dio what was what they're being accused off
unconscious bias. This is really a tough one on one that's actually quite fascinating to me,
but it's the idea of unconscious bias. It's the idea that sometimes we have biases. We don't even realize
And oftentimes those unconscious biases are one of the two biases were about to talk about confirmation. Bias is where
we are biased towards
confirming a set of facts or set of ideas that we believe to be true.
The facts that are given to us by our clients
bias. Our inclination is to try to confirm that those air. In fact, true
whether or not and to the exclusion off other biases
and also halo or horn the idea that you're automatically bias predisposed toe either thinking that all people are good or all people are bad.
All people are guilty.
All people are innocent,
and in our
this is different from the idea of innocent until proven guilty.
But it's the idea that your bias see that you could be biased
towards just towards either believing that everybody is good or everyone is bad, that everyone is innocents or everyone is guilty.
the idea that
you're going to find evidence that's going to either prove or disprove
your inherent your built in your unconscious bias.
What are the dangers of biases?
Well, they can lead to self fulfilling conclusions,
that confirmation, bias, that bias, that I'm gonna prove
what I what I need to prove, and I'm gonna do it come hell or high water.
So you open yourself up to creating conclusions that air self fulfilling where you find the evidence and you're you only look at the evidence in a way that
identifies it and makes it
self fulfilling to you or to your client
biases can also lead to a misinterpretation of evidence.
You might find that the evidence says that the individual
had a proclivity for looking at pornographic material.
But because you've met the person
because you or because you have a
halo or halo or horn Biasi,
you might say that can't be. This person wouldn't do it
there. Are there the pastor of the church,
They're the rabbi at a synagogue.
There's no way
your bias he has led you to misinterpret the evidence.
The other problem is that you might improperly discount evidence.
Well, this person would never do this. This person would never do that. So
we got to just believe that this evidence isn't telling us the truth.
The evidence is the evidence, the fax or the fax. And it's important that we set aside our biases and that we look at the fax
through clear lens and say, Is this reasonable?
Does Could this explain what it's meant to explain? And of course, there's gonna be caveats. Of course, there's gonna be
couching of your conclusions off course. There's going to be some element where you're going to say it could be this, but it also could be this,
and that's not improperly discounting evidence or misinterpreting or building self fulfilling conclusions.
It's just the case that
something maybe one thing or the other or multiple multitude of different things.
So it's important to not improperly discount evidence
because that may lead to
misinform during correct
conclusions or opinions.
In this video, we talked about how to recognize and address biases in the investigative process.
