So most of the personality tests that we've been talking about the big five, and even the Myers Briggs, things like that are done with s data, which is known as survey data, or self report data as well. So it's interviews or it is filling out questionnaires. Most research on personality is done using interviews and self report, it is easy to obtain, there's the idea of who knows you better than you. So most of the time, that's what we use. But it's not the only way you can assess personality. So another way is observer report or what they call old data. So a lot of times, you know, looking at something like the big five, they might have a spouse fill it out, or a teacher or someone else. So what do you observe? Sometimes we don't accurately report. And so maybe the spouse would or maybe just getting, you know, your friend or someone else to report about you. So you can still use questionnaires, interviews, things like that using observer report. There's also test data. And this is looking not at survey testing, but it's looking at a lot of times physiological test, or standardized test, as far as how does someone respond when I put you in this circumstance? I add a little bit of this to my research. So I often do things like skin conductance. So you know, you can report on how much anxiety you feel, or how easily distressed you are, as Dr. Deal was talking about earlier, but is that accurate? You know, can you accurately report that? So a lot of my research, we do things like we hook you up to skin conductance and show videos. So do you have a response to that? And then we can relate that to these different personality assessments and how you've completed things. We've looked at that related to like empathy, and, you know, response to abuse and things like that. So that's a form of test data. Also, how do you respond in things like, you know, so are you a leader? If I put you in a group setting? Are you going to take over and be the leadership? You know, are you going to be conscientious in this setting? So test data is just another good way to get the information we put you in a setting either physiological or environmental, how are you going to respond? And then the last one is L data, which is life outcome data. You don't find out as much about personality with this, but it's going to be things like maybe you know how many times you've been married, how many speeding tickets, you've got things like that real real world information. So if I'm looking at Are you a conscientious individual, are you responsible Are you following through, and you have a whole lot of speeding tickets, I might say no, because that's not a responsible thing to do. So I can kind of get a little bit with that. So now that we know a little bit about the data, what does your research say about which test is the most reliable or accurate? So I'll give you the answer I give my classes. Currently, the big five has the most consensus in psychology. It's been used in more languages, it's been used in different formats. So you know, when we're talking about personality test, it does have different formats. So Dr. Deal is talking about that any Oh, there's different formats for it. But the big five overall has the most consensus than any other trait taxonomy. So I would say that, in a broad overarching sense, there's more research behind it currently. So you know, there's different ways that we come up with these different taxonomies these different traits, and it's got a lexical approach, meaning language, it's got statistica l approach. So I'd say there's more research behind it, and it's more used.
