Was Today’s Poverty Determined in 1000 B.C.?
That is one implication of a provocative new study that compares countries’ economies today with their level of technological development millenia ago.
Not surprising when you think about it. Fast food is pretty expensive when you're making less than $10/hour.
A dangerous myth about who eats fast food is completely false
Rich parents might look down on fast food, but it’s actually their kids who eat it the most.

1. Eyewitnesses are highly reliable.
research shows that eyewitness identifications are highly unreliable…Yet, courts have been slow in allowing defendants to present expert evidence on the fallibility of eyewitnesses; many courts still don’t allow it. Few, if any, courts instruct juries on the pitfalls of eyewitness identification or caution them to be skeptical of eyewitness testimony.
2. Fingerprint evidence is foolproof.
When tested by rigorous scientific methods, fingerprint examiners turn out to have a significant error rate.
3. Forensic evidence of other types are scientifically proven and infallible.
Spectrographic voice identification error rates are as high as 63%, depending on the type of voice sample tested. Handwriting error rates average around 40% and sometimes approach 100%. False-positive error rates for bite marks run as high as 64%. Those for microscopic hair comparisons are about 12% (using results of mitochondrial DNA testing as the criterion).
4. DNA evidence is infallible.
… DNA evidence is only as good as the weakest link in the chain.
5. Human memories are reliable.
The mind not only distorts and embellishes memories, but a variety of external factors can affect how memories are retrieved and described. In an early study by cognitive psychologist Elizabeth Loftus, people were shown videos of car accidents and then questioned about what they saw.26 The group asked how fast the cars were going when they “smashed” into each other estimated 6.5 mph faster than the group asked how fast the cars were going when they “hit” each other.27 A week later, almost a third of those who were asked about the “smash” recalled seeing broken glass, even though there was none.
6. Confessions are infallible because innocent people do not confess.
Innocent people do confess with surprising regularity. Harsh interrogation tactics, a variant of Stockholm syndrome, the desire to end the ordeal, emotional and financial exhaustion, family considerations and the youth or feeble-mindedness of the suspect can result in remarkably detailed confessions that are later shown to be utterly false.
7. Juries follow instructions.
This is a presumption-actually more of a guess-that we’ve elevated to a rule of law.35 It is, of course, necessary that we do so because it links the jury’s fact-finding process to the law. In fact, however, we know very little about what juries actually do when they decide cases.36 Do they consider the instructions at all? Do they consider all of the instructions or focus on only some? Do they understand the instructions or are they confused? We don’t really know
8. Prosecutors play fair.
The U.S. Justice Department, for example, takes the position that exculpatory evidence must be produced only if it is material.
9. The prosecution is at a disadvantage because of reasonable doubt.
To the extent this psychological research is applicable to trials, it tends to refute the notion that the prosecution pulls the heavy oar in criminal cases. We believe that it does because we assume juries go about deciding cases by accurately remembering all the testimony and weighing each piece of evidence in a linear fashion, selecting which to believe based on assessment of its credibility or plausibility. The reality may be quite different. It may be that jurors start forming a mental picture of the events in question as soon as they first hear about them from the prosecution witnesses.
10. Police are objective.
And not just small-town police in Podunk or Timbuktu. Just the other day, “[t]he Justice Department and FBI  formally acknowledged that nearly every examiner in an elite FBI forensic unit gave flawed testimony in almost all [of the 268] trials in which they offered evidence against criminal defendants over more than a two-decade period before 2000.”49 Do they offer a class at Quantico called “Fudging Your Results To Get A Conviction” or “Lying On TheStand 101”? How can you trust the professionalism and objectivity of police anywhere after an admission like that?
11. Guilty pleas are proof of guilt.
… this fails to take into account the trend of bringing multiple counts for a single incident—thereby vastly increasing the risk of a life-shattering sentence in case of conviction56—as well as the creativity of prosecutors in hatching up criminal cases where no crime exists57 and the overcriminalization of virtually every aspect of American life.
12. Long sentences deter crime.
As with much else in the law, the connection between punishment and deterrence remains mysterious. We make our decisions based on faith
