New study disproves theory that goldfish only have a three-second memory
Your goldfish remembers.

A beautiful goldfish, with a great memory.
It’s long been a common belief that fish have the memory capacity of only a few seconds. People often make fun of people with bad short-term memory by saying they have the “memory of a goldfish.”
This belief about fish spread even further after being highlighted in Disney’s “Finding Nemo” films where Dory, played by Ellen DeGeneres, has a memory that lasts only about 10 seconds. However, a new study from Oxford University may have just proved that we got Dory all wrong.
To find out if goldfish have memories, the team at the University of Oxford trained nine goldfish to swim 2.3 feet and back to get a reward. Yes, goldfish are even smart enough to be trained. All these years they’ve been swimming in circles in small bowls when we could have been teaching them to do some fun behaviors.
The researchers marked off the tank in vertical stripes every ¾ inch.
Once the fish swam the 2.3 feet, they were given a physical cue from a researcher to turn around and swim back to where they started. If they did so, they’d receive a tasty bloodworm.
After the fish got that pattern down, the researchers changed the starting point and didn’t give any cues to turn back. Eight out of the nine fish swam the same exact distance before turning around. It seems that the fish used external cues to mark the distance and then turned around at the appropriate point. This type of measurement is known by scientists as “optic flow.”
This proves that fish actually do have decent memories.
The one thing that tripped the fish up was when the vertical stripes were moved closer together, they didn’t swim as far before turning back.
The fish also didn’t appear to use time as a way of marking distance.
“We did not find a significant effect of time on the distance travelled and the coefficient of variation in time travelled was two to three times higher than the coefficient of variation in distance estimate for most fish,” the researchers wrote. “Video analysis revealed high variation in time spent to perform the experiment within a day or a session without any apparent pattern, further supporting this hypothesis.”
This study definitely changes the way people will look at the film “Finding Dory” and how they relate to their goldfish. Remember that time you forgot to feed him? He remembers.
“Forgetful people say they have a mind like a goldfish, but that’s not fair,” Dr. Adelaide Sibeaux, who led the study at the University of Oxford, told Daily Mail. “Goldfish are clearly not stupid at all, as they have a good memory for distance based on the flow of objects passing by as they swim, like stripes on their tanks.”
“Even when I left for a week for Christmas, and came back to restart the study, they knew how to do it,” she continued.
So next time someone tells you they have the memory of a goldfish, let them know that it’s actually a compliment.

12 non-threatening leadership strategies for women
We mustn't hurt a man's feelings.
Men and the feels.
Note: This an excerpt is from Sarah Cooper's book, How to Be Successful Without Hurting Men's Feelings.
In this fast-paced business world, female leaders need to make sure they're not perceived as pushy, aggressive, or competent.
One way to do that is to alter your leadership style to account for the fragile male ego.
Should men accept powerful women and not feel threatened by them? Yes. Is that asking too much?
IS IT?
Sorry, I didn't mean to get aggressive there. Anyhoo, here are twelve non-threatening leadership strategies for women.
Encourage.

When setting a deadline, ask your coworker what he thinks of doing something, instead of just asking him to get it done. This makes him feel less like you're telling him what to do and more like you care about his opinions.
Sharing ideas.

When sharing your ideas, overconfidence is a killer. You don't want your male coworkers to think you're getting all uppity. Instead, downplay your ideas as just "thinking out loud," "throwing something out there," or sharing something "dumb," "random," or "crazy."
Email requests.

Pepper your emails with exclamation marks and emojis so you don't come across as too clear or direct. Your lack of efficient communication will make you seem more approachable.
Idea sharing.
With permission from Sarah Cooper.
If a male coworker steals your idea in a meeting, thank him for it. Give him kudos for how he explained your idea so clearly. And let's face it, no one might've ever heard it if he hadn't repeated it.
Sexism.
With permission from Sarah Cooper.
When you hear a sexist comment, the awkward laugh is key. Practice your awkward laugh at home, with your friends and family, and in the mirror. Make sure you sound truly delighted even as your soul is dying inside.
Mansplain.

Men love explaining things. But when he's explaining something and you already know that, it might be tempting to say, "I already know that." Instead, have him explain it to you over and over again. It will make him feel useful and will give you some time to think about how to avoid him in the future.
Mistakes.
With permission from Sarah Cooper.
Pointing out a mistake is always risky so it's important to always apologize for noticing the mistake and then make sure that no one thinks you're too sure about it. People will appreciate your "hey what do I know?!" sensibilities.
Promotions.
With permission from Sarah Cooper.
Asking your manager for a promotion could make you seem power- hungry, opportunistic, and transparent. Instead, ask a male coworker to vouch for you. Have your coworker tell your manager you'd be great for the role even though you don't really want it. This will make you more likely to actually get that promotion.
Rude.

Sometimes not everyone is properly introduced at the start of a meeting. Don't take it personally even if it happens to you all the time, and certainly don't stop the meeting from moving forward to introduce yourself. Sending a quick note afterward is the best way to introduce yourself without seeming too self-important.
Interruptions.
With permission from Sarah Cooper.
When you get interrupted, you might be tempted to just continue talking or even ask if you can finish what you were saying. This is treacherous territory. Instead, simply stop talking. The path of least resistance is silence.
Collaboration.
With permission from Sarah Cooper.
When collaborating with a man, type using only one finger. Skill and speed are very off-putting.
Disagreements.
With permission from Sarah Cooper.
When all else fails, wear a mustache so everyone sees you as more man-like. This will cancel out any need to change your leadership style. In fact, you may even get a quick promotion!
In conclusion...
With permission from Sarah Cooper.
Many women have discovered the secret power of non-threatening leadership. We call it a "secret power" because no one else actually knows about it. We keep our power hidden within ourselves so that it doesn't frighten and intimidate others. That's what makes us the true unsung heroes of the corporate world.
