Similar misusages of precision terminology abound in articles, discussion board postings, student exam responses, newspapers, and all other sorts of communication media. Too often, one sees sentences such as "The IRS held that . . . "

One of the things that might contribute to the imprecise transposition of terminology that has negative effects is the message that I received years ago in an English literature class. It is a message that I think is being repeated throughout the years and throughout education systems. I was told, “Aside from common words such as articles and prepositions, don’t use the same word more than once, especially on the same page. Buy a thesaurus.” That might be good advice for a novelist or poet, but it is atrocious advice for those who write in technical areas. Lawyers, engineers, physicians, scientists, actuaries, accountants, and those in other technically-focused professions can create confusing and even dangerous if not fatal errors when they use different words to mean the same thing. * * * * *
My rejection of imprecision, by students and by others, at times has been derided as picky or worse. But I usually quiet the complaints by asking if people want neurosurgeons operating on them, their children, or their parents to be imprecise. I wonder if people want engineers building bridges to be imprecise. I ask whether the folks making pet food, medicines, and other products should be imprecise. * * * * *
So it was no surprise to me when reader Morris directed my attention to a recent article titled, “Tax Deductions: Is College Tuition Tax Deductible?”, and pointed out a serious error. In the article, Amanda Dixon correctly noted that “The deduction for tuition and fees is not available for the 2019 tax year.” She then repeated that observation, stating, “The deduction for college tuition and fees is no longer available.” She followed that sentence with this one: “However, you can still help yourself with college expenses through other deductions, such as the American Opportunity Tax Credit and the Lifetime Learning Credit.” Whoa! As reader Morris commented to me, “The AOTC and LLC are tax credits not deductions.” He gets an A. Dixon does not. Credits reduce tax liability, whereas deductions reduce taxable income.
In Credit? Deduction? Federal? State? Precision MattersI wrote:
One of the core principles that students need to learn in a basic federal income tax course is the difference between a deduction and a credit. Deductions are subtracting in computing taxable income. Credits are subtracted in computing tax. A one-dollar credit reduces tax by one dollar. A one-dollar deduction reduces taxable income by one dollar, ignoring limitations, floors, ceilings, and other complexities, and a one-dollar reduction in taxable income reduces tax by something between a penny and perhaps 40 cents. In other words, in most cases, credits are more valuable than deductions.Indeed.

Precision matters. Lack of precision causes misunderstandings in communication, which can lead to all sorts of problems. Lack of precision causes engineering defects, which can lead to all sorts of problems. Lack of precision causes medical misdiagnoses, which can lead to all sorts of problems. In other words, to the chagrin of those who detest details and want to live in the world of sound bites and 140-character tweets, lack of precision leads to all sorts of problems.
Note: The Dixon article on which I commented was written before Pub. L. 116-94 extended the termination date of the deduction of tuition and fees. Pub. L. 116-94 became law in late December 2019. So the statement, "The deduction for tuition and fees is not available for the 2019 tax year" now is incorrect. The Dixon article now carries a date of 23 Jan 2020, almost two weeks *after* the preceding commentary was published. It still contains the statement, "The deduction for tuition and fees is not available for the 2019 tax year." The description of the American Opportunity Tax Credit and the Lifetime Learning Credit as "other deductions" also remains in the 23 Jan 2020 version of the article.
