Now, I am a mint-chip ice cream (-loving) person myself, and dismiss vanilla* for being merely useful as an ingredient base for other treats. And of course, I’m entitled to my opinion. In turn, you all are free to express your own opinions about flavours of ice cream, including your total disinterest in eating ice cream.
(* It may be that I lack some kind of flavour receptor[s] to fully perceive vanilla/vanillin, because no matter what sort of sweet or quality of material, vanilla has never seemed to be particularly interesting or tasty to me.)
But there are opinions and there are other opinions, and Patrick Stokes, Lecturer in Philosophy at Deakin University, teaches his students that they are not entitled to have their opinions.
In a recent article, “No, you’re not entitled to your opinion” he immediately acknowledges this sounds a bit harsh, but explains that the point of a philosophy class is learning how to create sound arguments, instead of leaning on beliefs, emotions, and misconceptions of what we think we know. Although opinions may be owned or expressed, not all opinions are equally valid.
Stokes skillfully distinguishes between the different things that fall under the vast umbrella of opinion:
But “opinion” ranges from tastes or preferences, through views about questions that concern most people such as prudence or politics, to views grounded in technical expertise, such as legal or scientific opinions.
It’s the conflating of being able to express one’s tastes, preferences, and beliefs — and then expecting those statements to be taken as seriously as fact-based, logically-sound argument — that is the major problem.
It is a major problem in everyday discourse, and in heated debates within and between countries, and it is an especially prevalent problem in various media. There’s the tired trope* of “getting balance” by interviewing “both sides” even though there are often more than just two sides (life is messy that way), and the problem that the opinions of both “sides” do not necessarily carry the same factual value (life is reality-based that way).
(* More on the problems with the news media and “balance” in my earlier post, “Both Sides Now”.)
Not all the information one finds or hears is equally valid. As Daniel Patrick Moynihan said, “You’re entitled to your own opinions, but not your own facts.”
Stokes further explains:
The problem with “I’m entitled to my opinion” is that, all too often, it’s used to shelter beliefs that should have been abandoned. It becomes shorthand for “I can say or think whatever I like” – and by extension, continuing to argue is somehow disrespectful. And this attitude feeds, I suggest, into the false equivalence between experts and non-experts that is an increasingly pernicious feature of our public discourse.
Wait a minute — can’t anyone have an opinion about anything? Of course!
Can’t anyone express their opinion about anything? Of course!*
(* Although it really helps if people take the time to ensure their protest signs are properly spelled and punctuated. Otherwise much hilarity ensues and one ends up with derisive and/or dismissive infamy rather than being taken seriously.)
But what unfounded opinion cannot do is carry equal weight when discussions require expertise.
Back to our ice cream opinions: I know that vanilla bean pods come from a variety of orchid, because that’s a tidbit of horticultural knowledge and I am a horticulturalist. Being a foodie, I have long known that vanillin was synthesized as a less-expensive alternative for use in commercial products, and that it is the primary ingredient in the artificially-flavoured vanilla extract sold at the market.
BUT, I cannot be an expert witness or speaker on vanilla.
Likely, neither can the majority of you.
Not on the cultivars, growing, agri-ecology, processing from raw material to diverse flavouring forms, business economics, grower’s social justice issues, distribution and packaging, artificial synthesis of vanillin, culinary chemistry, historical usage, future trends of natural versus artificial flavouring … none of that stuff. Nor anything else that didn’t come to mind, albeit I was able to come up with a longish list just because I have that horticultural background and was able to extrapolate what accessory topics could be included.
You are entitled to have and to express your opinion, but that does not mean it must to be taken as serious fact; pointing that out is not being disrespectful to you as a person — it means that your opinion is insufficient to the case.
‘Personal Opinion’ is not some cloak of factual immunity that one can wear to suddenly become a creditable expert.
(Oh, and speaking of public persons with opinions but who are not experts, guess who came along to comment upon Stokes’ article …)
Oh, boy howdy! This article by Laura Hibbard, “Texas Republican Party Calls For Abstinence Only Sex Ed, Corporal Punishment In Schools” nearly made me choke on my cuppa tea. She described just a few of the details the 2012 Republican Party of Texas wants for their state schools. (The article also includes a nicely scrollable copy of their entire Platform Report.)
You know me, I’m a science person, with keen interests in education and social justice. And I was flabbergasted. It’s like a car crash — you can’t help but gawp in horrified fascination. Well, I had the day off work, so after a house-painting break, scanned through most of the document. It’s one thing to hear soundbites on the radio or in video, but quite another to actually be able to read an entire position. For one thing, it gives a person the chance to notice internal inconsistencies, and look things up.
In addition to the aforementioned items listed in the title of Hibbard’s article, the Texas GOP’s document lists a lot more in their “Educating Our Children” section. For example, they also want to eliminate preschool and kindergarten, and require daily pledges of allegiance to the US & Texas flags (because that somehow makes one patriotic).
Ooh, get this:
“Classroom Expenditures for Staff – We support having 80% of school district payroll expenses of professional staff of a school district be full-time classroom teachers.”
You realize that means giving the ability to hire a number of part-time classroom teachers (and paraprofessionals if they opt to include some) who can be paid WAY less, which will keep a district’s budget way down. “Fiscal responsibility” as a loophole for loading up on part-time staff. Who of course often don’t get benefits — unfortunately, a common practice in education and other industries. (Yes, I’m calling education an industry.)
And of course, this next incredible ::head-desk:: concept that (for me) underpins a great deal of their platform:
“Knowledge-Based Education – We oppose the teaching of Higher Order Thinking Skills (HOTS) (values clarification), critical thinking skills and similar programs that are simply a relabeling of Outcome-Based Education (OBE) (mastery learning) which focus on behavior modification and have the purpose of challenging the student’s fixed beliefs and undermining parental authority.”
Because you know, mastering the subject material and learning how to think critically will undermine the GOP’s fixed beliefs and enable challenging authority. Any challenges to authority will be dealt with accordingly:
“Classroom Discipline –We recommend that local school boards and classroom teachers be given more authority to deal with disciplinary problems. Corporal punishment is effective and legal in Texas.”
Under the “Promoting Individual Freedom and Personal Safety” section, this concept continues as, Continue reading What Would Molly Ivins Say?
… but the Woo is giving off bad vibrations!
OhMyGosh the world is full of idiots! Tonight I was stocking over in the health foods section, which is either a great place (for our large selection of gluten-free products for coeliacs) or a magnet for all people woo-stricken.
A woman came to the grocery wanting “bread made without yeast” — I gestured to the big display of matzo (unleavened for Passover), but no, she wants loaf bread, but without yeast so her son “doesn’t get yeast infections”. I tried to explain they’re not even the same kinds of yeast, and it’d be dead after the bread’s baked anyway, but NO-O-O-O…
Yeasts are a kind of fungus: yeast called Saccharomyces cerevisiae is necessary for yeast-breads, beer and wine fermentation. For sourdough breads, a variety of wild yeast Candida milleri plus acid-producing bacteria Lactobacillus sanfrancisco that gives the dough the distinctive “tang”.
For our confused customer, the yeast infection [mouth, digestive tract, vagina] is from an entirely different fungus, Candida albicans.
If you’re curious, the fuzzy black stuff that grows on bread is a mold, Rhizopus nigricans. Molds are another kind of fungus. Yummy blue cheeses [Maytag blue, Dana-blu, Gorgonzola, Roquefort, Stilton] are made possible from the mold Penicillium roqueforti or Penicillium glaucum that were naturally present in the [naturally cool] caves where the cheeses were made & aged. (Nowadays the cheese wheels are injected with the appropriate mold). A few people with Penicillin antibiotic allergy may have a reaction to blue cheeses, but the quantity of the material is so much smaller in the cheese, it is rarely a problem.
I almost mentioned yogurt as a source of probiotics — I was “this close” — but refrained. Trying to add bacteria to her mental mix of Bad Things We Can’t Pronounce & Must Avoid would have been too much for the both of us.
Related to fungi (well, related just in the sense of small organisms helpful to food), are bacteria. Most of the bacteria that exist in the world are neutral to humans, and many are beneficial. Only a relatively small number are responsible for bacterial infections. Truth be told, we NEED bacteria, because they are responsible for the fermentation processes that turn raw food items into different, processed food items that have better/different flavor, are more digestible, and store for long periods of time. Some examples of these great bacteria include: Continue reading I'm picking up good fermentations
to 1994. Just the ordinary sort of 1994, when my children were two and six years old.
We are watching X-Men during Saturday morning cartoons. My son is really into super-heroes, and in case you don’t know, the X-Men are mutant super-heroes.
My daughter asks me, “What’s a mutant?” I take a deep breath, trying to figure out how to explain genetic mutation to a six-year old. Thankfully, with my children this wasn’t too difficult.
“Remember the other week when I told you what DNA is? The instructions that tell the different parts of your body how to grow?” She remembers. “Sometimes the DNA changes, and that’s called a mutation. A Monoceratops changing into a Triceratops s a mutation.”* We watch some more of the cartoon.
She asks me, “Are all mutants weird like the X-Men, and have super powers?”
“No. That’s just the cartoon part. If you always have yellow flowers and suddenly get a red flower, that’s a mutation. In fact, everything in the world started out as a mutation, or else there would be nothing but itty-bitty plants floating in the ocean.”
She decides that would be boring.
“Why do those people hate the X-Men? The X-Men are good guys.”
“They hate them because they’re bigots. ‘Bigots’ means when people hate other people because of something like what church they go to, or where they’re from, or how they look. The people hate the X-Men because they look different, and can do different things, and they’re scared of them.”
“But that’s not fair,” she complains, “The X-Men are nice.”
“That’s right. Bigotry isn’t fair, and it isn’t nice.”
“I like Storm the best.”
Storm is a black woman with long white hair who can control the weather, and fly. “Me, too.” I answer.
“I want to be Storm for Halloween.”
A few nights later, we are reading The Enormous Egg by Oliver Butterworth. This is one of my favorite stories from when I was growing up, a tall tale about a Triceratops dinosaur that somehow hatches from an egg laid by a chicken, and the consequences for the boy in the story. She has loved dinosaurs since she was a mere tot of two. We read two chapters into the book. She read a few paragraphs, sounding out new words, and then realised, “The chicken laid a mutant egg!”
This is why you should watch television with your children. In one Saturday morning cartoon, we have covered biology and bigotry, and made a tentative Halloween costume decision.
* I know, I know, it’s more complex than that. All you evolutionary biologists out there will have to work with me on that. (-;
Bug G. Membracid recently had a radio show appearance! (Is it called an “appearance” when you’re on a wireless programme and no one can see you? Nevermind.)
But it featured her line about honeybees being ”little flying phalluses” – which is really funny when you remember that worker honeybees are girls!
That in turn reminded me of a story during a horticultural study tour to a Dutch production greenhouse …
Tomatoes and peppers do not need insects to transfer pollen between flowers, as the flowers are “perfect” (have both male & female parts). But for the pollen to get moved/bumped from the pistils to the stigma there still needs to be some kind of wind or other vibration.
There’s not enough wind for this to naturally happen (or rather, efficiently happen) in a greenhouse, especially when the panes are shut to the weather. So it used to be that the operators would equip their greenhouse workers with *little vibrating wands* (oh yes), which they used to buzz-pollinate Every. Single. Fresh. Flower. (Insert inevitable sniggers from the undergrads.) Of course, that’s a lot of paid worker hours.
Nowadays the thrifty Dutch use bumblebees, who work for much cheaper wages of cardboard nesting boxes and some supplemental nectar. The big, gentle bees still visit all the flowers for the pollen, and resultant heavy buzzing results in flower fertilization for good crops.
[N.B. Derf; “cucumbers in the title is incorrect – they DO need to be insect pollinated! Except of course for the parthenogenetic cukes, which basically set fruit by a sort of “virgin birth” process…]
One of my favorite blogs has another great one:
(We keep our dish soap on the counter, in a small pump bottle to meter out doses, and to use less counter space.)
So I go into the kitchen to catch up on some dishwashing, and find a small puddle of goo on the counter. “Is the barometric pressure dropping?” I ask the family as I sponge it up, and proceed to do my washing-up.
“It’s supposed to snow on Sunday,” answers my son-in-law.
Well, that explains a lot. Firstly, the reason the soap has drooled onto the counter is because the barometric pressure outside the bottle is now lower than inside the bottle. (I filled and re-sealed it a couple days ago.) The fluid seeps out because fluids go from areas of high pressure to areas of low pressure.*
Out of typical insatiable curiosity (“More input!”), I then check out my local weather data site. This explains the second question. No wonder I have a headache; the barometric pressure has dropped about 15 millibars in the past day, from the general maxima down to the general minima. Barometric pressure hoo-hahs are one of my headache/migraine triggers.
Sometimes I wish I lived on the space station, where the air pressure is kept constant. (Besides, I could grow my veggies, herbs and flowers without all the dang pests.)
* AKA “Why do we have to learn this stuff?” Well, now you know — no one squeezed dish soap onto the counter and left a mess; it happened because of natural forces.
