I do like that Kevin distinguished between this case and the previous ones, saying that all the facts of this case makes it different from the other two cases, where very rare and low probabilities were involved. At first, I was thinking "Wait, what if the signature match was also a coincidence that actually occurred, and maybe the aunt did have a legitimate earlier will?" I'm glad I waited until the vid ended before commenting lol.

Basic cursive with a couple unique touches is a good way to sign. For example, I combine the first letter of my last and first name. The letters are B and P and I combine them similarly to how the E and B are combined in the Bugatti logo. This makes a clearly intentional way to sign that you would have to know and wouldn't be able to make up.

This could have been prevented if there was a written proof of her signing this thing and depositing it in a central bank to known persons with shared access. Then if anyone came up with such a testament out of nowhere, it would have to have a verifying letter in the central bank, else it'd be invalid. Such, it would never even have occurred, since the person who could testament never wrote a verifying letter with discrete shared access to the witnesses, nor is she alive to be accounted for it. Relevance? I'm delevoping a new justice paradigm based on mathematical logic. Previously unsecured transactions become self-verifying like a logical hamming code.

Hi. Mind some science-youtuber-recommendations?

When I left school, I had a job for a year or so in my local Unemployment Benefit Office aka Dole Office, as a clerk processing "Fresh Claims". Every document the claimant submitted had to be countersigned or initialled by me. I quickly found out that if I had missed a document, one of my colleagues in the back office would forge my initials on the form or whatever. In his head, he was doing both the claimant and myself a favour by making sure the claimant got what was due, and that I didn't get a bollocking for not signing off the forms correctly. My head still rings with "Yes, but.....!!"

Great series you got going on. Keep up the great work!

Basically: use probability as the final nail in the coffin, not as the foundation for a case? Probability is circumstantial, and while (contrary to popular belief) it's possible to convict someone on circumstantial evidence alone, what you're looking for in that case are things that, coming together independently, fit into a pattern. This forms a strong foundation for a case, rather than your evidence being stacked haphazardly on top of each other like you're playing Jenga. When you _start_ with probability as the core of a case without compensating for how the result biases the investigation going forward, you're going to be building a Jenga tower that can come crashing down at any time, because whatever you find next will _rely_ on that first result being correct to make any sense. And while independently intersecting coincidences make you _more_ confident that you're correct, if those coincidences _depend_ on one another due to factors that cause bias, the probability of being _incorrect_ rises dramatically. A shoddy case like described above is essentially like a chain: if there's a weak link in it, that's where it snaps, and all the effort you put in after that point is not just wasted, but outright misleading, since you fit it to an incorrect assumption. The more links a chain like that has, the more likely that at least one will fail, even if they're all decently strong. Making sure your evidence arises independently does not lengthen an unreliable chain, but creates parallel connections that strengthen the core of your case.

Really loving these deep-dive forensic analysis videos, keep em coming!

You should create more videos like that, i love ittt! I can't believe i listen to you more than to my prof 😁

One of my philosophy profs always pronounced C.S. Peirce's name as "purse" instead of "pierce" (probably because of its spelling?) and that is what I most remember from his class. I don't even know if it's the right pronunciation, but it's what I have taken from that class.

The odds of the signature being an exact match was 100 time less likely than ten billion second human century, so yeah that was impossible.

It's very interesting. I have signed my name 20-30 times when I need to and they don't match at all. It's almost impossible to sign your name the same over and over.

I thought she would have faked the signature too bad but I never thought about it beeing to good. So I was confused about the huge standard deviations in Kevins signature. I guess they are plenty of other ways to compare signatures? Like loops and other types of strokes

I loved the comparison to the other cases at the end. I think this is also the reason why she was never convicted of fraud because the standard of proof is much higher than in civil court and they would have needed more concrete evidence that she made the forgery herself.

Good video 👍 Thanks

This video is almost in stark contrast to a VSauce video I just got done watching that explained using probability to prove something is not always as "cut and dry" as it seems. Whenever some "expert" claims that a probability is "one in a gazillion" (gazillion = some number over one million), my red flags start going up.

I'm always reminded of how sh*t my signature is. I have horrible handwriting in general, and I write slow even though it's sloppy. So my signature was literally just my initials with random squiggles where other letters should be. There is no reason to take more time because nobody can read it anyway. Over the years, it has devolved to just my initials and a wavy line. It always makes me wonder if I could just draw a smiley face on official documents and nobody would say anything, ever.

Damn, here I was proud that my signatures are all perfectly identical to each other and in reality some nerd could claim it was faked? So I've been undoing myself by being consistent and using something I can perfectly repeat rather than just generally repeat? I better change my signature!

My signature is so different each time that I live in constant fear of being charged or something 😅
