How do we know that sulfuric acid does not cure scurvy? Is it our wonderful intuitive sense about sulfuric acid’s properties? That can’t be it. Vitriol (sulfuric acid) used to be the Royal College of Physicians’ favored choice. The British Admiralty preferred vinegar. Still others favored a variety of remedies including the seemingly ridiculous notion of fresh fruit. This mess wasn’t sorted out until a young Scottish naval surgeon named James Lind did something revolutionary. In 1747 Lind conducted world’s first controlled clinical trial. Fresh fruit won, sulfuric acid and vinegar lost.
Similarly, there are various untested claims about which architectural interventions are beneficial for individuals with autism (see: here, here, here, and here). For the most part, these claims are mired in anecdote and conjecture. This makes it impossible to decipher which ones are sulfuric acid, vinegar or fresh fruit. Fortunately there are a few architects that have started to embrace the Lind spirit. This is the most important and necessary step architects need to take. If architects do not try to verify their claims through fair tests then they run the risk of undermining the public’s trust or worse, unintentionally doing harm to a vulnerable population.
