       | 
       | The combination of understanding code, aircraft dynamics, and
       | existing patents was complex. It was made more so by the attempt
       | by other avionics manufacturers to design around the patents and
       | write the code sufficiently differently.

       | an expert in something very niche, there might not be enough
       | cases in a given year to give you a meaningful income.

       | lucrative if your expertise is in high demand, like personal
       | injury or medical malpractice.

         | Is the notion that a person contributes a set amount of value

       | It should be noted that, in the context of a legal proceeding,
       | "expertise" is both broader and narrower than the common usage.
       | "Broader" in the sense that evidentiary law rigidly distinguishes
       | between fact testimony, which for the most part is the testimony
       | of people with personal knowledge of the facts, from expert
       | testimony. As a result, the latter can include things like
       | accounting, summarizing, or analyzing financial numbers to
       | calculate damages.
       | 
       | On the other hand, the Supreme Court's decision in _Daubert v.
       | Merrill Dow_ imposes the requirement that expertise be based on
       | "reliable" methods. That would arguably exclude a number of
       | academic discipline that aren't based on such methods.

       | My company, Root Labs, has consulted on various lawsuits. We

       | reverse engineering and writing a detailed technical analysis of
       | how a product works. This report was then reviewed by the
       | testifying expert, who wrote their own report to be entered as
       | evidence.
       | 
       | I recommend not working as a testifying expert for a few reasons:
       | 
       | - You have to take sides, and the other side will never want to
       | work with you again. Are you sure you'll never want to work with
       | AT&T if you represented Verizon once, for example? What if you
       | want a job there some day?
       | 
       | - Despite the term "expert", it comes down to how you present
       | yourself in the courtroom versus what you know. The opponent's
       | "expert" might seem more believable than you, despite being wrong
       | about the technical issues.
       | 
       | - You have to stick to one particular area of technology your
       | whole career, and many of the cases cover the same ground. Do you
       | want to be "Ethernet Implementation Person" your whole life?
       | 
       | - A lot of the work is boring, and lawyers are generally not
       | technically adept. Juries are worse. So if you love explaining
       | something repeatedly in oversimplified terms, maybe you'd like
       | this.
       | 
       | Usually testifying experts are older and do it after they've
       | finished a career in some subject area. It might make sense at
       | that point as a second career.

               | But consider criminal trials, which often turn on expert
               | testimony. There you have a big asymmetry between the
               | government prosecutors (who come into court with a _de

               | resourced public defender. An officer 's suspicions or

               | testimony more notable for its intensity than its
               | applicability; the jury is encouraged to imagine the
               | worst-case scenario rather than assess the probability
               | that it happens. The quality of forensic evidence and
               | procedures can and does fall short of scientific rigor.
               | Often this involves unscientific claims of perfect

               | Sometimes expert witnesses are just not qualified. During
               | the last presidential campaign a woman alleged she had
               | been sexually assaulted by Joe Biden when he was a US
               | senator, which naturally attracted journalistic scrutiny.
               | She had previously been an expert witness on sexual
               | assault in 10 criminal cases, based on credentials and
               | experience. Subsequent investigation (first by the media,
               | later by a DA's office) established that she did not hold
               | the academic qualification she claimed to have, though
               | whether this claim was rooted in misunderstanding or
               | mendacity was not established. I don't believe her
               | testimony was dispositive in those trials, but in all 10
               | her credentials were accepted rather than verified.
               | 
               | A big issue in US law arises out of the adversarial
               | nature of the legal system: even where expert testimony
               | may be invalid or outright false, if it is not
               | successfully challenged at the trial stage then it is
               | very difficult to raise its invalidity as an issue at
               | appeal after conviction/litigation. You could have proof
               | or even an admission of unreliability, and that might be
               | fully accepted by the appeal court, but an unjust
               | conviction might be upheld on the basis that the expert
               | witnesses' expertise or testimony should have been
               | impeached at or before the trial stage, and the defense's
               | failure to do so was a strategic error rather than a
               | failure of the court. This is exacerbated by the fact
               | that appeal courts consider only arguments of law, but
               | not of fact. The overall good of the legal process is
               | given greater weight than the reliability of any
               | individual outcome; in practice, a certain amount of

               | or a new trial in the original court. Years can pass

             | "Hidden camera" scenes involve a second hidden camera, only

             | move from side to side and up and down, and back and forth,
             | that's the real you, that's different. People in general
             | look like they look in the mirror, it's the shitty photos
             | with tiny little cameras that make them look like shit, and
             | often distort the image to neg them, like in 1984 when the

             | makeup on him, plus the lighting, everything. When I was
             | scouted as a model and went to castings the cameras were
             | invariably bigger than the eye of a squid. A tiny camera
             | can only take a good picture with photoshop, it's super
             | distorted and can't be placed on a phone except for crappy
             | images (like photos of contracts). Anything else is trying

             | an alternative to name-calling and dragging people down
             | like in more raw fighting. So criminals are when they're in
             | crazy arrogance mode continually insulting and degrading
             | their victim as loud as possible.
             | 
             | There's also a huge amount of ad hominem masquerading as
             | accusations of ad hominem, like "my ad hominem doesn't
             | count as ad hominem" or "you're not a hominem." Prejudging
