Panda Bears and Flowers / Clever Hans

Yep, it happened again, I murdered another plush toy to make a cute bag out of it.

Inappropriate-guilty-feelings aside, I am actually so happy with this panda bear backpack. And I bought him for $3 from an op shop (yes, it's a male panda bear), so at least there were no sentimental attachments there. If you missed it the first time around, I wrote up some instructions on how to make a DIY plush toy bag here. The only difference with this one is that I added two straps (thrifted belts) instead of one!
My pretty floral blouse & red skirt are both from Sheinside! Many thanks to Sheinside for providing them to style!

If you're a casual reader of science stories (or have joined IFLS on facebook) you may have heard people talking about "blinding", or that an experiment was not reliable because it wasn't "blinded" or even "double-blinded". You may have thought, what on earth does "blinding" mean and more importantly, how on earth does anyone know what's happening if no one can see what's going on??

Well "blinding" is one of the most important concepts to science. Human beings, clever as we may be, are unfortunately very susceptible to something called bias - that is, seeing what you want to believe.

That's where the story of Clever Hans comes in. Clever Hans was the name of a horse who lived in the early 1900s. His owner claimed that Clever Hans could not only count, but could also do complex maths problems and understand German. His owner would ask him questions, and Clever Hans would answer by tapping his foot. His owner paraded his horse around Germany, showing off his apparent skills.

Clever Hans was investigated by veterinarians and teachers. They removed the audience to make sure Clever Hans wasn't getting cues from them, and they even used different questioners (other than the horse's owner) to rule out the possibility of fraud.
Then they made a realisation - if the person asking the questions knew the answer to the questions, then Clever Hans would get the right answer 89% of the time. But if the person asking the questions didn't know the answers themselves, Clever Hans was only right 6% of the time.

It seemed that Clever Hans was clever in a way, although he didn't know how to count or do maths - he had learnt to tap his foot whenever the questioner expected the horse to tap its foot. Take away the expectations of the questioner, and the horse had no idea.

This was a very important observation for science and where the idea of "double blinding" comes from. Now scientists make sure, especially in fields where animals or humans are being measured, that not only does the participant not know what condition they are in, but the experimenter is also "blind" to the conditions of the experiment as well. Only at the end of the experiment, when all the tests have been done, are both the subject and experimenter allowed to know what was really going on. And that's your neat science fact of the day.

Fairy Bread, Sleepy Head

Check out these Oasap tights! *Droooool*. Aren't they awesome? (They're not super dooper thin either, if you're thinking of purchasing them!) And yes, I cut a fringe into my new wig - and I'm not sure if I made it better or worse. Time will tell...

Why do we yawn? One of my new favourite science bloggers, Katie from the Molecular Circus, tried to answer this question on her blog the other day. It's a really interesting read! There are several theories as to why we yawn, and science still doesn't really know - my favourite theory is the empathy one, but it's likely there are a couple of reasons for the existence of yawning. (Click here to read her post!)
Also, did I make all you guys yawn with all this talk of yawning? No? How about a photo - will that help?
*YAWN*

Hope you're all having a happy day!

Lace & Hearts / Mind Reading & Barnum

As promised yesterday, here is my new Choies wig and Yes Walker flats together in an outfit! It is super dooper hot weather today (Australia doesn't seem to understand that it is autumn yet), but I really wanted to wear these tights, so I paired it all with this simple, summery lace dress from Koogal.

Okay, guys. For something different today, I'm going to tell you, yes you, reading right now, some things about yourself. Before you read below, just read this list of qualities, and take tick each one off if it applies to you. And then ask yourself - does Annika know me? Has she read my mind?? (Didn't you guys know that I can read minds now?)

So, here goes -
Most of the time you are positive and cheerful, but there is a time in the past where you were very upset.
At times you feel very sure of yourself, whereas other times you are not as confident.
You have a need for other people to like and admire you, and yet you tend to be critical of yourself.
At times you have serious doubts whether you have made the right decision or done the right thing, but generally you have had a positive influence on the people in your life.

You have just experienced what is known in psychology as "The Barnum Effect". Popular with astrology sections in magazines and psychics, the Barnum effect shows how easily we can be manipulated into believing that the vaguest statements are actually meaningful insights into our own lives.

Think about the above sentences. Did they apply to you? They probably also applied to most of the people reading this post.
Okay, so it's likely you thought this test in particular was silly, because it's obvious that I, Annika, am not going to know all about you and your personality through some kind of psychic blogger powers.

But this test, when given by some kind of authority figure (or by someone who claims to have 'mysterious powers') works extremely well. In fact, the original "Barnum test" was masked as a "personality test" (just like a self-test you might find in a trashy mag), in which psychology students in the 1940s had to answer some questions on their personality. They were then all given pieces of paper with "feedback", and asked to rate how well it applied to themselves. Most gave it a rating of 4 to 5 out of 5 for accuracy. Only afterwards was it disclosed that all the "feedback" given was entirely identical to everyone elses.

Our brains are interesting things, and it's good to know how your own one can be fooled ;)

I hope you're all super well,
