Latest modern science | Critique: Manta ray thoughts - Si Bejo Science

This week�s contribution comes from Kenneth Chin. Click to enlarge!


Let me get to a couple of good things before moving to the ways it could be improved. First, the title is big and cannot be missed. If a title truly is 90% of your communication effort (as I�ve argued elsewhere), this poster is ahead of the game.

Second, there are lots of pictures of charismatic animals, including up at the top at eye level. It helps to have a subject that people generally like. I don�t know of anyone who hates manta rays.

Third, the main organization is a simple pair of columns. The reading order is not confusing.

That said, there are more frustrating things on this poster than good things. This poster is a compendium of common pitfalls.

There is way to much text, way too close together. That the poster is so dense calls attention to awkward dead spaces in the poster, shown in red below.


I tried a quick and dirty edit to move sections apart by shrinking the text and images a bit. I also took away the box around the conclusions and bar chart.

Even though the edit creates its own problems (makes alignment worse), it now has a little room to breath.

In the edit above, I flipped the order of the figures. Originally, Figure 7 appears on top of Figure 6. Also, there are two diagrams labelled �Figure 5.�

While the text is a clean sans serif, the bulk of it would be better in regular type instead of italics.

This poster needs to go back almost to the very beginning. The strongest course of action would be to give this poster a ruthless edit. Cut down the amount of material dramatically. Keep one big picture of a manta ray, show one graph of data, and list one to three major conclusions instead of nine(!).

But there is room for improvement even without going back that far in concept. Take off almost all the text and pictures. Make a grid. Draw lines for two evenly spaced columns, with a wide space between them, and wide margins. Make all those text and picture edges line up perfectly. Make sure every text block is an inch from pictures, and vice versa.

A clean two column layout is hidden deep in this poster; I can see hints of it. A disciplined adherence to a grid would reveal it, and leave an acceptable poster.

After I wrote all of the above, but before Kenneth had read it, he sent me a new version of his poster:


We�d converged on many of the same solutions! The major one is that the poster is now in two clean columns. Regarding the italicized text, he�s suffering form some mystery software glitch: they�re not supposed to be in italics.

Latest modern science | Present your geology poster online! - Si Bejo Science



Signal boost!

The American Geophysical Union just tweeted out  a link to a virtual poster competition for undergraduates. You have to sign up my 3 March 2016 for the spring round. Anyone who wants their poster critiqued beforehand... my email address is not hard to find.

Additional: When I retweeted the link, Terry McGlynn responded:

AGU meets in San Fran, too $$ for students. The fix? Just put them on the internet. They need a real network too!

This is a valid point. Is a �virtual poster session� the academic equivalent of the �kiddie pool�: intended to be a safe environment, but kind of demeaning at some point?

Latest modern science | Critique: Autotune - Si Bejo Science

This week�s poster from Chris Cummins (used with permission) is not about correcting pop stars who cannot sing on key. This was presented at the computer science conference HiPEAC 2016. Click to enlarge!


My first reaction when I opened the file was, �A magazine cover!� The title band, the big graphic central graphic surrounded by short bursts of copy all look like a magazine to me. The biggest visual clue was the �5X speedup!� circle is very reminiscent of the sort of thing you see on magazines all the time. You can see this on this MacUser cover:


I enjoy the overall appearance of the poster so much that the tweaks I might suggest are fairly small.

The red highlights in the text are dark and potentially difficult to read. While it doesn�t do it in this case, red on blue together can cause an effect called stereopsis:






I tried lightening the textual highlights (�expensive,� �automate,� �Omnitune� just a bit to match the red in the �5X� circle:


The difference is subtle, but the reds aren�t vanishing into the dark blue behind them quite as much as before.

There are at least four fonts in play on this poster, which is more than I normally recommend. It works, though, as the you often see a lot of play on fonts in magazine covers.

The subheadings seem to be set in Impact. I might have tried looking for a different font, because Impact has been used so much in recent years that it�s starting to look a bit tired. Worse, Impact is almost universally used in LOLcats and memes, so that font might signal silliness more than serious scholarship. On the other hand, memes do say �Internet and computers,� so that might not be a bad thing for a poster on computation.

Like last week�s poster, this one doesn�t treat authors equally. Instead, it emphasizes who is the presenting author in two ways. First, it uses colour. Not only is the presenting author�s name in a highlight colour (red), the other authors�s names are put in alight gray, rather than white. Second, it uses contact information to emphasize who you should send questions to: only the presenting author�s name gets an email address.


Like a good magazine cover, this poster is great at saying to conference goers, �Hey you! Yes you! Come across the hall and read me!� The potential problem is that in a magazine, you can flip into the covers to find more depth and details in the actual articles. A poster can�t provide that. It�s difficult for me to tell whether an aficionado has the key details that he or she would like.

Latest modern science | Critique: Gull movements - Si Bejo Science

Today�s poster is courtesy of Christine Anderson. This was presented at last year�s World Seabird Conference. Spoiler alert: this poster contains seabirds. Click to enlarge!


Christine wrote that she was a blog reader, and posts like this and this inspired her.

Many things work on this poster. Neither the big, big title nor the picture of the gull can be missed. The picture being in a circle helps draw in the eye. The choice of colours, I think determined by the maps, is generally harmonious.

One of the unusual things about this poster is how it handles the author list. There are six authors, but the lead is quite a bit bigger than the others. I am guessing that Christine was the presenting author, and thus the only person at the poster during presentation time. This might have some advantages for the reader, as it allows you to identify who the presenter is quickly. On the other hand, having the presenting author�s name larger than those of the co-authors might be viewed as a downplaying of the contributions of the other authors.But then again, just the ordering of names does that.

This technique probably can�t work if the presenting author is not the first author. It would look dumb if the author list was:

Christine Anderson
Mark Mallory
Grant Gilchrist
Rob Ronconi
Chip Wesloh
Dan Clark

There are two things that might improve this poster.

First, almost everything could do with some more generous margins. The poster looks a little crowded. The Figure 1 legend looks like it�s just about set to bump into the latitude numbers on the neighbouring map.

Second, the recommendation for a little more spaciousness also applies to the text. The crowded feeling isn�t helped by the bullets. If you�re going to have bulleted lists, I like them set with hanging indents, like this:


I also added 6 points after each paragraph.

Christine wrote that the poster got a good reception, which I am always pleased to hear!

Latest modern science | Link roundup for January 2016 - Si Bejo Science

We have a new contender for �worst graph ever�: the pie cloud.


What... I mean... Why... I... I give up. Shudder. Hat tip to Andrew Gelman.

Pieter Torrez has an article on how to create a beautiful scientific poster.There�s good advice on use of colours, text, software tools. The only thing I�m not sure I agree with is adding a picture of yourself.

Eve Heaton decided to use the trick that every conference vendor learned long ago to attract passers-by:


Hat tip to Colin Purrington.

Because PowerPoint is so often used to make posters as well as presentations, I have to link to this long, thorough analysis of PowerPoint�s history and use. The history is impeccable, although the analysis of PowerPoint�s importance is variable and sometimes told in fancy academese instead of plain English. Here�s an excerpt I like (that applies to poster presentations, too):

Rich Gold, manager of the Research in Experimental Documents group at Xerox PARC and self-proclaimed PowerPoint maestro, characterized presentations as jazz. Slides are merely the starting point, the �bass rhythm, and chord changes over which the melody is improvised.� ... Reading from notes or slides violates the expectation that a speaker can lay it down fresh every time, connecting with the group around a commonly held artifact.




Check out the list of 2015�s most popular fonts. Plenty of gorgeous fonts, though quite a few would only be good in very small doses on an academic poster.

Latest modern science | Critique: Thale cress RNA - Si Bejo Science

Today�s poster is from Andrzej Zielezinski. It was shown at the twentieth annual meeting of the RNA Society last year. Click to enlarge!


This poster feels very contemporary and in tune with the times. The style is very close to �flat design� seen a lot on the web: clean, primary colours, sans serif type, very little shading. (Indeed, the website mentioned on the poster has a similar aesthetic.) I love how the core of the poster (the intro, methods, and results) looks.

The abstract is problematic. At a distance or shrunk down, that big rectangle in the upper left just dominates the poster�s visuals. It draws you in, and give you... blocks of text as a reward.

I would have tried to lighten up that block so it isn�t so visually dominant. In this quick and dirty redo, I�ve made the text that nice green, for emphasis, but put the box into a lighter, more neutral grey.



It�s not quite right, but I think the balance is a little better. The better solution would be to remove it entirely!

The grey stripes in the background are subtle enough that they are not overwhelming. Like the abstract, however, they might be lightened up around the edges f the poster a bit. The stripes are running at three different angles, too: the set running across the bottom is not lining up with the upper left. And if the stripes are going to radiate out from the center of the poster, maybe they should do that in all the corners.

The title bar is unusual: very few people right align their titles, because that�s not where we are trained to read. In this case, because you have that big abstract block in the upper left, having the title on the left too would have been far too much. Having space around the abstract block helps the overall look of the poster.

The title text feels a little light. Because it is set in a low contrast light green in a thin font, with a few grey stripes behind it, it might not be easily readable or noticeable from a distance.

I�m a little puzzled that a website link shows up in two places: under the authors� affiliations, and down in the bottom green bar. I would be tempted to have it in one place alone. My instinct would be to cut the top one, so I could make the title and author�s section a bit roomier, or maybe larger.

Similarly, I can�t quite figure out why two logos are sensibly corralled in the bottom, while one is taking a primo spot in the title bar. I�m guessing the one in the title is the institution and the others are funding agencies?

The genus and species names (Arabidopis thaliana) are not in italics anywhere. My reaction:

Latest modern science | Critique: Sea turtles eating trash - Si Bejo Science

This week�s poster is like those �Spot the difference� cartoons that used to appear in the classified ad section of newspapers (dating myself there). Qamar Schuyler sent me a work in progress, so there are two versions. You can click either to enlarge!


There�s a lot to like. The sea turtle provides a clear cue as to what this poster is about. I wonder if a picture of a turtle ingesting debris might be an even better indicator of the poster�s topic. The trade-off could be that a poster of a turtle in trouble might be disheartening and a turn-off to a potential reader. Maybe the healthy, charismatic turtle used here is the right choice.

The main data, the maps, are up front and center. The big coloured map is placed just where it should be: right in the upper middle. The caption for it, though, is a little problematic, because it�s been severed from the image it describes.


In general, you want to place descriptive text as close to the image it�s linked to as possible.

A similar problem occurs with the smaller maps. While they don�t have to be read in any particular order, they do wind around, snake-like, between the colour map and the captions.


Part of the problem here is that five maps are the same size, and one � for Kemp�s Ridley sea turtle � is narrower. I would still try to put these in a more consistent two by three grid, and just suck up that the last one isn�t a perfect fit. Perhaps the figure caption could slot into the extra space, maybe like this:


Or this:


Of course, I�ve cheated in the sketches above because I haven�t relocated any of the text. Repositioning the figures would require a massive revision of the right side of the poster, perhaps moving the �Results� section into the upper right corner.

Here�s Qamar�s tweaked version. Spot the differences!


Some of the differences I caught (not intended to be an exhaustive list):

  • The box around the conclusions has been given a red border to �pop� the take home message. I like it.
  • A graph has been added to results. I like this, too. Visuals are better than words.
  • A poster number has been added. I�m very mildly against this, because I��m not sure it does much besides take up space. On the other hand, it is unobtrusive and might help someone.
  • The proportions have changed a little.
  • The �Contact me� box in the lower right has been tweaked a bit, and is better aligned with the box above it. I would like it more if it was the same width as the box above, though.

You can see this poster with Qamar at the Ocean Sciences meeting in New Orleans in February. If you can�t make it to the Big Easy, you can read the pre-print of the article here.
