There is a long history of witness testimony being given an excessive amount of weight in American trials. One prominent example of this is the Salem Witch Trials.

In January of 1692, two young girls (9-year-old Elizabeth Parris and 11-year-old Abigail Williams) from Salem Village, Massachusetts, began having fits, including violent contortions and uncontrollable screaming. Although a modern study suggests that these fits were the result of the children consuming the fungus ergot, which can be found in rye, wheat, and other cereals, at the time, the local doctor diagnosed bewitchment. Shortly thereafter, other young girls in the community began to exhibit similar symptoms, and three local women were arrested after the girls accused them of witchcraft. 

Two of the women denied using witchcraft, however, the third, Tituba, a slave from the Caribbean confessed, probably hoping to save herself by acting as an informer. As part of her confession, Tituba claimed that there were other witches in the community that had acted alongside her.

This led to mass hysteria within the town of Salem, and soon many more people had been accused of and arrested for witchcraft. In the trials that followed, the primary evidence that was used for a conviction was witness testimony. In fact, some of the witness testimony that was presented wasn’t given by people who had seen the accused practicing witchcraft, but by people who had had dreams or visions of the accused practicing witchcraft. Altogether 19 people were hanged for witchcraft, 7 accused witches died in jail, and one man was pressed to death by stones for refusing to plea.

Eventually the trials were deemed unlawful, and in 1711 Massachusetts Colony passed legislation that restored the good names of those convicted of witchcraft, as well as provided financial restitution for their heirs. In 1953, Arthur Miller used the Salem Witch Trials as the basis for his play “The Crucible,” which he published during the Red Scare (a time of growing fear against communism during the 1950s) in an attempt to remind Americans not to rely primarily on witness testimony when judging innocence or guilt.

In 1893, the case Nix v.s. Hedden found its way to the American Supreme Court. In this case, John Nix, John W. Nix, and Frank W. Nix filed a suit against Edward Hedden, a collector at the Port of New York, who had charged them a vegetable tax on their imported tomatoes.

The Nixes argued that, because a tomato is, botanically speaking, a fruit, the vegetable tax shouldn’t have applied.

At the trial, dictionary definitions were ignored, because, according to the Court, “dictionaries are admitted, not as evidence, but only as aids to the memory and understanding of the court.”

Instead, the Court looked at such things as the “ordinary meaning” of the words “fruit” and “vegetable” and precedent. In 1889, the case Robertson v. Salomon had established that, although technically white beans were seeds, they were eaten like vegetables instead of planted, so they should be taxed as a vegetable.

Ultimately, the court decided that a tomato should be taxed as a vegetable. The opinion of the court read: “Botanically speaking, tomatoes are the fruit of a vine, just as are cucumbers, squashes, beans, and peas.

But in the common language of the people, whether sellers or consumers of provisions, all these are vegetables which are grown in kitchen gardens, and which, whether eaten cooked or raw, are, like potatoes, carrots, parsnips, turnips, beets, cauliflower, cabbage, celery, and lettuce, usually served at dinner in, with, or after the soup, fish, or meats which constitute the principal part of the repast, and not, like fruits generally, as dessert.”
