When he arrived at Kraft's attic, Lucius found one mottled color block picture after another nailed to the wall, arranged from the corner to the door.
There are small fitting squares scattered around the edges of the black and white picture, with narrow and zigzag gaps passing through them, but most of them are almost stuck together. However, if you look carefully, you can still find the difference from the density of diagonal lines filled in the squares.
After hearing this, Kraft showed him a large stack of paper in his hand, which was the result of more than half a month. "I filled these in on the map. It would probably be more intuitive to express them with images."
"White means getting better?" Lucius looked at the map for a while and asked.
"No, on the contrary, the black ones are the better parts."
Kraft handed the record paper to Lucius and pointed out the small crosses and horizontal lines on it. "I call it a positive effect if it crosses it horizontally or vertically, and it means a negative effect or invalidity if it is a single horizontal line. But it doesn't matter how you name it."
, you just need to remember that the former should be blackened on the map to indicate the degree of improvement."
"For each additional one, I will draw more diagonal lines and blacken it in the corresponding small box. Since they do not have accurate timing tools, they all rely on subjective judgment, so the credibility of these information..."
Lucius scratched his head. He felt that there might be nothing more accurate than the patient's subjective feeling. From the simplest point of view, I know my own body best, right?
Kraft turned over a few pages of information and pointed out the weird ones in the records of the past few days to him one by one, "Especially these ones that change a lot every day and jump back and forth. It cannot be ruled out that there are indeed
It's possible, but it's too much."
"Look at this. When we went there yesterday, they all came back with water, and they told us that they just woke up not long ago. The nearest water point is obviously far away."
Lucius continued to scratch his head. The new well had not been completed yet, and it took a long time to get back and forth to the nearest water intake point. Of course there was a problem. But he didn't understand why someone would do this.
"If he lied, I don't understand why he did that. What's his name?" After looking at the record on the paper, I couldn't identify what the name Kraft wrote was for a moment.
The first-hand record of Kraft is rarely shown to anyone. Most of the time, people read it on the paper that was copied and sorted out a second time. It is difficult not to suspect that it is because of the illegible handwriting and is only for the writer's subsequent rewriting reference.
Kraft glanced at it and replied without hesitation: "Call Coop."
"Ah?" Lucius was puzzled. He looked at the artistic name with flying strokes again, but still couldn't pronounce it.
"I wrote down a separate piece of paper for some things that were different, and then marked them with blue on the picture. This one is just the most outrageous one." In this case, Kraft didn't have any good ideas, "The best thing is.
The solution is to spend more time.”
Lucius weighed the paper in his hand. He couldn't believe that the weight was the result of their visits little by little. "Can you still find time?"
"It's too difficult. Maybe they all have their own reasons. I can't figure out the reasons one by one. Once I figure it out, it won't be solved in a short time."
Looking at the maps on the wall, the black parts are expanding and getting thicker at a relatively uniform level.
During the first survey after deactivating the well water, only sporadic sparse lines were added to the map. On the third day, there were obvious changes in the map, like a handful of black beans sprinkled on it.
Afterwards, this trend became obvious, and the entire area was slowly improving. Most of the grids were filled with a little diagonal lines and became fuller. For the first time, the black color was so pleasing to the eye.
"So the presence of black liquid in the human body is indeed not permanent. If it is poured into well water to this degree of dilution, the effect will subside after a period of time after stopping use. By analogy, those who use ordinary diluent will be able to use it for a long enough time.
After some time, we will probably get rid of this possibility completely.”
As expected, an evenly spread improvement is taking place, and most people can see an obvious trend of the awakening time gradually moving forward.
This also allowed Kraft and Lucius to gain increasing trust and popularity in the salt tide area. They did not receive any substantial compensation, but the change in their attitude could be seen.
From obedience to the authority brought by force and status to true respect. Some people began to be willing to share more details with them, talking about the position of the sun when they last woke up, and comparing the height of the opposite roof.
.
Admittedly, a lot of the information was not particularly useful, but there was also a lot that, after conversion, effectively helped Craft calibrate his own investigation.
"This is good news." Lucius said. He watched Kraft pick up the pen and fill in a few more boxes in the new picture, then picked up the information on the table and compared the numbers, and found that there were no discrepancies.
"It's so scary..."
"What?"
"Your memory." Lucius sighed, "I thought you remembered those books verbatim because you memorized them for a long time, but I didn't expect that your memory is so good."
Craft couldn't answer this, so he could only say, "Maybe it's talent," which made Lucius make an envious and jealous sound.
Since Kraft didn't need help, Lucius was bored and looked at the map by himself.
Things presented in simplified diagrams do have a different feel, are more intuitive and easier to understand. He understood this when he read about the anatomy of the inguinal canal.
The author took a few minutes to read to explain where the aponeurosis and fascia come from, how they form the front, back, upper, lower and four walls that are extremely convoluted to carry on the back, and how the contents of the stomach come from this structure.
Ran out.
All put together, no picture is as simple and straightforward as that. So everyone likes pictures, especially simple and clear pictures, and Lucius is no exception.
He started from the corner of the wall and looked at it one by one, watching the black gradually spread out, from less to more, and reversely wrapped around a few areas with lighter colors.
The few light-colored areas can be seen clearly shrinking in the next picture, and are then divided and resolved by the new black areas.
There are also some completely untouched white areas that are dotted with inconspicuous blue paint. It is probably the patients who Kraft said were unable to determine the authenticity of their statements, who received special attention.
Some of the blue dots have been removed over time, but there are still many stuck in various places. It feels uncomfortable when you see them too much and makes you want to pick them out.
Once you notice some things, you can't get them out of your head. Lucius' attention drifted involuntarily to the blue dots, paying attention to the changes around them. After looking at them for a long time, he really found some patterns.
Logically speaking, the overall dyeing sequence of black patches should be even, so there won't be light spots that last too long.
But there is a difference near the blue dot. It is not the kind of difference caused by one or two survey differences, but it exists continuously.
At first, when there are many white patches, they are not obvious. After most of them are blackened, they gradually become highlighted.
"uh-huh?"
For the sake of rigor, Lucius walked back to the previous pictures and compared them repeatedly to confirm his findings.
There seems to be a lag in the color patch surrounding the abnormal blue spot, at least about two days slower than the approximate average rate of change, which is the time between surveys.
"Weird?"
I went to the table and pulled out some tissue paper, traced the rough outline of the light-colored area, and then marked the position of the blue dot in this area.
"Craft, can this area be drawn first in this map?" Lucius pointed to the area he found near the center of the map and roughly circled a range, "I have an idea, but I don't know.
affim."
The interrupted Kraft looked at the corresponding data on the plot he circled and seemed less surprised, "You also think the color change of this plot is different?"
"Did you already know this?" Lucius was a little disappointed. He thought he had discovered something extraordinary.
"You can't say that. In fact, it's not just here, there are several places where this phenomenon has happened." Kraft walked along the wall and pointed out several small patches on the map that Lucius had not discovered just now.
They are lighter and lighter, and there are also many with blue spots.
"However, most of them didn't last long and disappeared within a few days. It turned out later that it was the bias caused by neighbors' tendency to communicate about their illnesses together, which affected both subjectivity and expression. This has only become apparent recently."
"Okay, I'm so weird now." Lucius spread his hands and put down the paper.
The paper was taken by another hand, "Do you think that blue dot is the center?"
"Yes, I looked around the blue dot. I know the two probably have nothing to do with each other. If I'm to blame, I blame them for being too conspicuous."
Kraft leaned over and observed for a while, then continued to write on the map, and quickly completed the new map of this area alone.
"It's not unreasonable, Lucius."
A new rough stroke of the light color area is drawn, folded onto the previously drawn paper, and aligned according to the middle point.
Craft held several pieces of paper up to the sun, and the strong light passed through the jerry-rigged thin paper, stacking the graphics together.
"It's true that this area is shrinking, but it's basically shrinking around this point... It doesn't seem to be easy to explain?" He gestured with a pen and found that the progress in all directions had a similar trend, but there was no central flowering.
black block.
"Because this person not only doesn't believe you, but also speaks ill of you to the people around him?" Lucius drew inferences from one instance and immediately came up with an answer based on interpersonal relationships. His learning ability is very good.
"I'm glad you learned one of the important influencing factors of survey bias, but forced analogies are not advisable. Can you remind me to ask more questions there next time?"
"You are too modest. I don't know who can remind you of the things you forgot, except forgetting to eat." Remind Kraft that few people can do it. Lucius doesn't think he will be the exception. Listen to this.
Just fine.
"That's right." He knocked on the blue dot and asked curiously, "Who is this person? He's already here and still creating false information."
